Short Overview

Today I explored different methods for creating a resonance suppressor in Bitwig Studio. I walked through using modulators like the audio sidechain to dynamically reduce harsh frequencies, explained how to split signals with spectral tools for noise control, and demonstrated creative routing options for more visual feedback. There are many approaches, from simple EQ ducking to nerdier custom solutions inside Bitwig’s grid, so it really comes down to what sounds best and fits your workflow. Overall, Bitwig makes these processes intuitive and flexible with its native devices and modulation system.

Introduction and Channel Background

Today, I want to walk through resonance or harshness suppression in Bitwig Studio, inspired by a popular Ableton Live tutorial recently posted by Virgil Riot. While bigger channels might reach more people, Bitwig's flexible modulation system actually makes this process very easy, intuitive, and powerful. Even though I've shared similar techniques before, I want to give you clear and organized options for achieving intelligent resonance suppression in Bitwig with native devices.

The Envelope Follower Approach in Bitwig

Using EQ5 and Audio Sidechain Modulators

Let’s take a drum loop as our example. In Bitwig, resonance suppression can be quickly set up using the EQ5 and an audio sidechain modulator. This modulator acts as an envelope follower with configurable rise and fall times, plus filtering for focus on specific frequency regions, such as 1 kHz to 10 kHz.

By connecting this output to lower the gain on an EQ band, peaks in harsh frequency regions get reduced in real time. You can control the aggressiveness with amount dials, and Bitwig even lets you adjust the modulation curve (linear, exponential, or logarithmic) to fine-tune how the suppression reacts.

Multiband Control and Modulator Stacking

It’s also easy to control multiple frequency areas at once. Simply add more audio sidechain modulators, each focused on different frequency ranges, and map them to control different EQ bands. You can create complex, responsive dynamic EQ behaviors with no artificial limit to how many modulators you use.

Using the Same Technique with EQ+ and Other Devices

This same principle applies to other Bitwig EQs like EQ+. The workflow is just as simple, and the flexibility is identical, apply the modulator to any parameter you like.

Sidechaining and Track Spacing

A compelling use case is track spacing or dynamic sidechain EQing. For example, you could use a kick drum signal as an audio sidechain input to momentarily duck the bass fundamental in a bassline using an EQ band, creating space and reducing masking between kick and bass. This technique extends easily to any mixing scenario where you want one sound to make temporary room for another.

Spectral Processing with Loud Split

Bitwig’s Loud Split device offers another creative method. It’s a spectral processor that divides incoming sound into three bands (loud, mid, and quiet) based on a threshold.

Unlike the envelope follower and EQ approach, Loud Split applies a uniform reduction to all bins above the threshold so it’s effective for broad de-essing or noise gating but less precise or dynamic than the modulated EQ trick.

Combining Spectral and Modulated EQ

One advanced approach is to combine Loud Split processing with further dynamic control from an EQ and modulators. For example, insert an EQ after Loud Split’s loud band and use sidechain modulation as before for more surgical, reactive suppression.

Visual Feedback and Pre-FX EQ

Bitwig’s EQ+ allows reference inputs. By referencing the output of Loud Split (say, the loud chain post-processing), you can visually overlay the problematic peaks and relate them to your pink noise curve or custom reference spectrum.

Experimental Approaches: Using Filter+ and The Grid

Notch Filtering with Filter+ and Macro Controls

Bitwig’s Filter+ can be turned into a dynamic notch filter, and you can add envelope followers to control the amount of notch applied, following the detected resonance energy in the frequency of your choice. By using macro knobs, you can automate and bind both the detection filter and the EQ filter cutoff for precision suppression.

Advanced: Building a Notch or Peak Filter in The Grid

For the nerdier users, Bitwig’s modular Grid lets you hand-build a notch filter that’s dynamically linked to an envelope follower set to your frequency of interest. This approach includes:

This method is highly experimental and is largely for users wanting extreme control or educational exploration but demonstrates Bitwig’s internal flexibility.

Preset Workflow Suggestions

To make your workflow more efficient, build and save your favorite suppression setups as Bitwig presets. Whether for de-essing, transient taming, or complex track spacing, recall your custom chains instantly instead of rebuilding from scratch.

Conclusion

Bitwig Studio offers several robust ways to suppress resonances and dynamically control harshness natively:

These options offer powerful, creative tools for mixing and sound shaping, all with Bitwig’s immediate and visually rich interface. Choose the method that best fits your tastes and workflow, and remember to leverage presets for efficiency.

[00:00:00] Hey folks, welcome back.
[00:00:01] So I saw this on Reddit today from present policy,
[00:00:05] creating a resonance suppressor.
[00:00:07] I watched the recent YouTube tutorial from Virgil Riot
[00:00:09] where he uses an envelope follower
[00:00:11] to create a sort of a mini resonance suppressor
[00:00:13] in Avid Live.
[00:00:14] And this is basically my curse, my life curse
[00:00:17] that I have to recreate every possible Avid Live tutorial
[00:00:21] in Bitwig Studio and no one cares for my channel
[00:00:24] in the first place because I showed this a few years ago
[00:00:28] in Bitwig Studio already.
[00:00:30] It's very easy to do in Bitwig
[00:00:33] because we have all these modulators, but it's okay.
[00:00:36] It's not a problem for me.
[00:00:37] That's how it is, right?
[00:00:38] These are bigger channels
[00:00:39] and they are more spread around in the YouTube algorithm.
[00:00:43] So no problem.
[00:00:45] So in Avid Live, you have to use your EQ
[00:00:48] to filter out multiple signals.
[00:00:50] You use one signal right for the input as an input
[00:00:54] for the envelope follower on the second channel and so on.
[00:00:57] So in Bitwig, it's a bit easier.
[00:01:00] So here we have a drum loop and all we have to do
[00:01:05] is use random EQ, for instance, we can use the EQ5 here.
[00:01:10] And then instead of creating multiple copies
[00:01:14] of the same channel,
[00:01:15] we can just use an audio side chain modulator
[00:01:20] and the audio side chain modulator is nothing else
[00:01:22] than just an envelope follower here with the rise
[00:01:24] and fall time and also on top, a low cut and a high cut.
[00:01:29] So we can filter out already what we want to analyze.
[00:01:34] And here we maybe focus on the 1K to 10K region, right?
[00:01:39] And you get here an envelope follower signal
[00:01:43] on the left side, as you can see.
[00:01:45] And we can then use this to pull down here
[00:01:48] the fourth note of the EQ
[00:01:50] and it just reduces the frequency.
[00:01:55] (drumming)
[00:01:57] And we can influence here the amount.
[00:01:59] (drumming)
[00:02:02] And also interestingly, if you select the modulator
[00:02:07] on the left side of Bitwig, we have here this modulation list.
[00:02:12] You can see here, this is our modulation
[00:02:14] and we can change, what's the name here?
[00:02:17] The modulation curve.
[00:02:22] So at the moment it's linear, flat response,
[00:02:24] but you can also change it to exponential
[00:02:27] and also logarithmic.
[00:02:29] So it has a different feel to it.
[00:02:32] So with exponential, you can see nothing really happens here.
[00:02:37] Just a bit of reduction there
[00:02:40] and you can increase here the loudness
[00:02:42] or the gain of the audio side chain
[00:02:44] so we get more signal into the analyzer.
[00:02:49] And then it reacts more drastically.
[00:02:51] (drumming)
[00:02:52] Then we reduce here the gain
[00:02:54] (drumming)
[00:02:55] or the amount of the modulation.
[00:02:57] (drumming)
[00:03:00] So this sounds more like a real compressor, in my opinion.
[00:03:10] We can also expand.
[00:03:12] (drumming)
[00:03:13] Right, going here into the negative range with the amount.
[00:03:17] (drumming)
[00:03:19] So the more frequencies there are here at the top,
[00:03:21] the more we push it up.
[00:03:22] So it's exactly the opposite thing we want to do.
[00:03:26] (drumming)
[00:03:28] You can also switch this to logarithmic.
[00:03:34] (drumming)
[00:03:36] So we have here in the first place a lot of gain reduction.
[00:03:39] (drumming)
[00:03:40] So it's more sensible to audio signals in the first place.
[00:03:44] (drumming)
[00:03:47] Maybe the modulation is too much here.
[00:03:50] We go to maybe only 3 dB.
[00:03:53] (drumming)
[00:03:56] Right, so you can see it reacts more sensible
[00:04:00] to audio input.
[00:04:02] So you can tweak it in all kinds of directions.
[00:04:06] It doesn't really matter.
[00:04:07] Or it only matters what kind of taste you have
[00:04:09] or what you want to do with your process,
[00:04:13] with your audio resonance suppressor.
[00:04:16] It really depends on your sound.
[00:04:17] So you can tweak it in all kinds of directions.
[00:04:20] We can also just duplicate here
[00:04:22] the audio sidechain modulator
[00:04:24] and focus on a completely different frequency range
[00:04:28] from one and two, I don't know what this is here.
[00:04:31] 300 hertz.
[00:04:32] And then completely change here the modulation
[00:04:39] to a gain reduction here on the third band.
[00:04:43] (drumming)
[00:04:45] On the second one.
[00:04:46] You can see it reacts differently
[00:04:52] to different inputs on different frequency regions.
[00:04:57] And you can do this to as many notes you want
[00:05:03] inside of an EQ.
[00:05:05] We can add as many modulators as you want
[00:05:09] in Bitwig, there's no limitation,
[00:05:11] which gives you unlimited options, of course, right?
[00:05:15] You can also do this, not only on the EQ five,
[00:05:17] you can also do this on the EQ plus, of course,
[00:05:20] it's the same thing here, audio sidechain modulator.
[00:05:25] And then add here a note, one K.
[00:05:31] Move this here to one K.
[00:05:34] And then make your gain reduction.
[00:05:38] (drumming)
[00:05:40] Very easy to set up, very easy to do,
[00:05:48] and very straightforward,
[00:05:49] you don't need to have any ideas of how EQs work
[00:05:54] or anything like this, you just set it up and it works.
[00:05:59] You can also use this to make room for other stuff.
[00:06:03] So you can, for instance, here select
[00:06:05] as an sidechain input a kick drum from another track
[00:06:09] and say here, this is my bass line.
[00:06:11] I want to remove the bass fundamental frequency here.
[00:06:14] Every time the kick drum comes in,
[00:06:17] maybe I can do this here quickly.
[00:06:21] So we have here kick drum with the low frequency, of course,
[00:06:27] and then we select the kick drum output.
[00:06:31] And then every time the kick drum plays,
[00:06:34] we reduce here the frequency.
[00:06:38] That's okay.
[00:06:42] (drumming)
[00:06:44] So also possible.
[00:06:50] So you can use this as a sidechain, as a track spacer,
[00:06:53] as a noise suppression or resonant suppressor
[00:06:57] or whatever you want to call it.
[00:06:58] And it just works straight out of the box
[00:07:02] with modulators in Bitwig Studio.
[00:07:04] Another thing you can do instead of using a cue,
[00:07:07] you can also use here the spectral device called loud split.
[00:07:11] And loud split just takes an audio input
[00:07:13] and splits it up into three parts, the loud part,
[00:07:16] the mid part and the quiet part.
[00:07:17] It sounds like this here.
[00:07:19] This is the loud part.
[00:07:23] So everything that peaks above this threshold here
[00:07:29] gets is pushed into the loud box here in the loud chain.
[00:07:34] (drumming)
[00:07:37] So this is the mid part.
[00:07:39] So everything that's not peaking above the red line.
[00:07:44] And then the quiet part.
[00:07:47] This is the noisy part.
[00:07:48] So basically, if you just mute the quiet part,
[00:07:54] it's a gate, a spectral gate.
[00:07:57] So everything that's here down here is just muted.
[00:08:00] (drumming)
[00:08:03] So you can remove noise if you want to.
[00:08:09] Then you can also do like muting here the loud part.
[00:08:15] (drumming)
[00:08:18] So everything that's peaking that's very loud
[00:08:21] is just completely removed in terms of bin.
[00:08:24] The frequency doesn't exist anymore,
[00:08:27] which is maybe not what you want
[00:08:30] because then you remove certain snare fundamentals here.
[00:08:34] Of course, completely, you completely remove it.
[00:08:37] (drumming)
[00:08:39] Right, all these red frequencies here you can see
[00:08:44] on the analyzer are completely removed, just non-existent.
[00:08:49] (drumming)
[00:08:52] So instead of doing this, muting here the loud channel,
[00:08:59] what we can do is we can just pull down the volume a bit.
[00:09:03] So you go here, you set this up to a certain point.
[00:09:07] So we have some of the loud parts peaking above the line.
[00:09:11] (drumming)
[00:09:14] And then you just pull it down by two DB or three DB
[00:09:19] or one DB, right?
[00:09:22] (drumming)
[00:09:24] And then the loud parts are just a bit quieter.
[00:09:27] They are not that upfront anymore.
[00:09:30] So it's already a noise suppressor here
[00:09:33] focused on the loud parts.
[00:09:36] We also have your tilt features.
[00:09:38] We can tilt the spectrum.
[00:09:39] I have it usually on plus three DB.
[00:09:42] So this equals to a pink noise curve,
[00:09:45] but you can also say I want to have a zero DB.
[00:09:48] (drumming)
[00:09:49] So with this, we have low end peaking
[00:09:53] very early above the line here.
[00:09:56] (drumming)
[00:09:59] Or we can go to 60B here.
[00:10:02] So then we only have here the top parts.
[00:10:04] (drumming)
[00:10:06] The harsh, the harshness, top end peaking
[00:10:09] above the loudness thing here.
[00:10:11] So we can focus on this area
[00:10:13] and just pull it down a bit in volume, minus five DB.
[00:10:18] So this is more like a de-esser.
[00:10:20] (drumming)
[00:10:25] (drumming)
[00:10:27] So this is what we pull down.
[00:10:30] (drumming)
[00:10:32] So instead of using any cue here, you use a spectral device
[00:10:42] and split it up into different parts.
[00:10:44] And then you pull down the parts
[00:10:46] that you don't like in volume
[00:10:48] or you completely remove it.
[00:10:50] And it has the same effect more or less.
[00:10:54] But yeah, this is not really dynamic
[00:10:56] because it pulls down all the bins by equal amounts.
[00:11:00] So like a minus five DB here, right?
[00:11:02] So everything that's above the line
[00:11:04] gets pulled down by minus five DB.
[00:11:07] But usually audio signals are dynamic.
[00:11:09] So they have different loudness levels, right?
[00:11:12] And they're peaking in different positions in time
[00:11:15] by different amounts.
[00:11:16] So it's not really reactive to that.
[00:11:18] So yeah, you can combine this here
[00:11:21] with the EQ method I showed you in the beginning.
[00:11:26] So we put here in the loud part,
[00:11:28] we put here in EQ five.
[00:11:30] (drumming)
[00:11:31] And you can see here in this EQ
[00:11:34] because we put this here on the loud chain,
[00:11:35] we only have here the top part in the analyzer.
[00:11:39] And here you can use then again,
[00:11:41] an audio side chain modulator
[00:11:44] and pull down here the top end
[00:11:47] by different amounts.
[00:11:52] In different points in time.
[00:11:54] So one K to 10 K here.
[00:11:59] Maybe disable this.
[00:12:03] Yeah, something like this.
[00:12:06] So this is now more reactive.
[00:12:09] You can also use your mutable audio side chain modulators
[00:12:13] of course for different parts here if you want to do that.
[00:12:16] And in my opinion, maybe do a preset for that.
[00:12:20] You don't want to set this up all the time,
[00:12:22] every time just make a preset for harsh frequencies
[00:12:25] or for the SR that you really like
[00:12:27] or for your voice or for your vocals.
[00:12:30] And then you just recall it every time
[00:12:32] and you have it ready to go
[00:12:34] instead of building this chain here every time from scratch.
[00:12:39] Another idea I already showed in some of my videos
[00:12:45] is that you can use here instead of EQ five,
[00:12:48] you can use what's the name EQ plus.
[00:12:51] So the EQ plus is interesting in that sense
[00:12:56] that we have some options here on the left side
[00:12:59] in the inspector.
[00:13:00] You can see we have here reference inputs.
[00:13:03] We can use a second signal
[00:13:05] and overlay it on the spectrum analyzer here
[00:13:08] to see what's going on on a different track
[00:13:10] on a different channel.
[00:13:12] But here we can use it to analyze what's going on
[00:13:16] in save the loud split.
[00:13:18] So in the loud split here,
[00:13:20] I usually just put a tool device in the loud chain here.
[00:13:25] And then I can use on EQ plus the reference input here
[00:13:29] and go to the same channel,
[00:13:31] loud split chains, loud tool out.
[00:13:34] And I get basically as an overlay here in purple,
[00:13:38] what's going on or actually only the frequency content
[00:13:42] that's peaking or leaking above the threshold here
[00:13:45] of this line, right?
[00:13:47] So what you can do with this is you can decide here
[00:13:50] to go for a 3 dB per octave tilt,
[00:13:53] then pull down here this threshold for the loud part
[00:13:58] until some of the frequencies are leaking through.
[00:14:01] And you can see this here in purple.
[00:14:02] We have a lot of content here around 200K
[00:14:07] and some content around 1K and one here above 10K,
[00:14:11] which is completely fine.
[00:14:13] But then you can use this basically to say,
[00:14:15] oh, I have to EQ here something.
[00:14:17] I have to EQ here and maybe I need to EQ here
[00:14:21] because here are the parts that are actually peaking
[00:14:24] above my pink noise curve
[00:14:27] or this 3 dB per octave curve here, right?
[00:14:30] But the problem here is you can EQ as much as you want
[00:14:35] the purple line or overlay stays
[00:14:38] because the loud split here in front
[00:14:42] doesn't get any info about what you do in this EQ here
[00:14:45] after the loud split.
[00:14:47] So you can do something funny in Bitwig.
[00:14:51] You can actually drag this EQ plus into the pre-FX chain
[00:14:55] of the loud split device,
[00:14:57] which then the loud split gets the information
[00:15:01] what's actually EQed here in this EQ plus.
[00:15:04] And then we get the information from the loud chain
[00:15:09] as an overlay, which means we can now EQ here
[00:15:12] out certain parts.
[00:15:14] And then you can see the purple overlay goes away
[00:15:17] in this part because we just EQ this out
[00:15:20] or we reduce the gain for this frequency,
[00:15:23] which then not leaks above the threshold here
[00:15:27] of the thread line anymore,
[00:15:28] which then is not used as an overlay in this EQ plus.
[00:15:32] This makes sense.
[00:15:33] So we have a visual information
[00:15:37] about where we need to EQ something maybe.
[00:15:40] And you can also get visual information
[00:15:45] if you actually EQed enough.
[00:15:46] So it's not leaking above the threshold line.
[00:15:51] And you can also tweak this here with the rise
[00:15:54] and four times of the loud split.
[00:15:57] So maybe go to eight here, four time eight.
[00:16:00] So it's not giving you information for every bin
[00:16:04] that's shortly peaking above the threshold,
[00:16:07] only for things that are long,
[00:16:09] for a longer time above the threshold.
[00:16:13] So yeah, actually what you want to EQ out.
[00:16:17] So here, this kind of stuff.
[00:16:20] This around 200 hertz, there's always something
[00:16:22] around 200 hertz of frequency that nobody likes.
[00:16:25] And also you have some harsh frequencies.
[00:16:29] And also here you can combine this
[00:16:31] with my trick in the beginning.
[00:16:33] Use here an audio side chain modulator
[00:16:35] and react to this frequency content here above one K
[00:16:42] or around 10 K.
[00:16:44] And then pull down here a frequency note.
[00:16:49] Something like this.
[00:16:53] Yeah, that's okay.
[00:16:58] Okay.
[00:16:59] So you have all kinds of options
[00:17:05] and possibilities in Bitwig,
[00:17:08] where you can combine devices and tricks
[00:17:10] and modulators to get this kind of idea out of the way.
[00:17:15] Or you can solve it in multiple different ways.
[00:17:19] And also everything has a different sound to it.
[00:17:23] So maybe you don't like the spectral sound
[00:17:25] of the loudspeed, so you can use the EQ.
[00:17:27] If you don't like the EQ,
[00:17:29] then you can use the loudspeed, okay?
[00:17:31] So these are the basic native things you can do
[00:17:34] in Bitwig here.
[00:17:36] There are probably more options.
[00:17:39] Something like I showed you, I think,
[00:17:41] in some of the recent videos.
[00:17:46] So we can use here, let's say,
[00:17:48] and filter plus device, which is also just an EQ.
[00:17:55] More or less, we don't need the distortion device here,
[00:17:58] but we can enable the filter
[00:18:00] and we can use here a notch, right?
[00:18:03] And I want to maybe use an EQ curve analyzer
[00:18:06] so you can see what's going on.
[00:18:08] Let's clone this.
[00:18:10] So here in the EQ curve analyzer,
[00:18:15] you can see it's a notch filter.
[00:18:16] We completely remove here a frequency.
[00:18:19] You can change the frequency, of course.
[00:18:22] And then you can pull down the mix
[00:18:25] of this filter plus device
[00:18:26] and this gives you the gain reduction.
[00:18:29] And here we can do the same thing.
[00:18:33] Again, we use an, what's the name?
[00:18:36] Audio side chain modulator.
[00:18:39] And we use here the,
[00:18:41] so instead of dialing this in your manually,
[00:18:45] we can go down with the low pass
[00:18:49] and with the high pass here, completely down to 20 Hertz.
[00:18:53] 20 Hertz.
[00:18:55] Then we use a macro knob here
[00:18:57] and modulators by 120 semitones,
[00:19:02] so the low cut and the high cut.
[00:19:04] So we can move this around.
[00:19:06] And we also start here with the notch filter by 20 Hertz.
[00:19:14] And then we go up here by also 120 semitones.
[00:19:19] So we end up in the same space, right?
[00:19:22] So now we have one macro knob where we can change
[00:19:24] the audio side chain focus frequency
[00:19:29] or the band pass frequency.
[00:19:31] So we analyze the signal.
[00:19:34] And then we have, at the same time,
[00:19:36] also here the notch filter,
[00:19:38] also at the same position in time, right?
[00:19:40] So we can change both these things at the same time.
[00:19:44] And then we use more or less here
[00:19:48] the envelope follower to modulate the mix.
[00:19:54] So every time we get the frequency there,
[00:19:57] it's probably not showing here because it's not enough.
[00:20:04] Yeah, but you can see it here.
[00:20:10] Yeah, so let's remove here the EQ analyzer
[00:20:13] and use the jumps again.
[00:20:14] Don't need the input here.
[00:20:21] So we can focus here around one K, one kilo Hertz.
[00:20:24] And you can see it, the audio envelope,
[00:20:27] the audio side chain envelope here reacts to the audio input
[00:20:31] and then it brings in here the mix,
[00:20:33] which then brings in the notch,
[00:20:34] which reduces the frequencies at this position.
[00:20:37] So this is also something you can do
[00:20:39] if you don't want to use the EQ for that.
[00:20:42] You can just use the filter plus device and the mix knob
[00:20:46] to bring in actually gain reduction
[00:20:49] in a certain frequency area.
[00:20:51] So this is also here.
[00:20:53] Yeah, I would say a noise suppressor
[00:20:57] or resonance suppressor or DSR or however you want to call it.
[00:21:02] So yeah, this also works too.
[00:21:04] Okay, and then there's another way that's a nerdy way.
[00:21:09] And the nerdy way is maybe so nerdy
[00:21:11] that you maybe don't want to watch the video until the end
[00:21:15] because it involves the FX grid of Bitwig Studio.
[00:21:20] And I already made a video about this here a few weeks
[00:21:24] or maybe a month ago about FFT.
[00:21:27] This is not really FFT, but it goes into the same direction.
[00:21:32] So what we want to do is we actually want to use
[00:21:34] the sine oscillator to figure out
[00:21:37] if there is frequency content in a certain area.
[00:21:41] And we can use the sine oscillator
[00:21:44] and we want to feed this here pitch.
[00:21:48] And I use here this frequency to pitch module, right?
[00:21:51] And feed this into the pitch input.
[00:21:53] I also disable here this one
[00:21:55] because we don't want to use the keyboard
[00:21:57] to change the frequency.
[00:21:58] And then we can use a constant
[00:22:02] and we switch this here from hertz to kilohertz.
[00:22:06] So now we can say this is one kilohertz
[00:22:09] and it gives us the right pitch for one kilohertz
[00:22:12] for the sine oscillator.
[00:22:14] Okay, so now we have a sine oscillator playing exactly
[00:22:17] at the pitch of one kilohertz.
[00:22:20] We can also see this here in the spectrum analyzer.
[00:22:22] Right, one kilohertz sine, very, yeah, nothing special.
[00:22:30] So what we want to do with sine
[00:22:31] is we want to use a dome filter
[00:22:33] and we split the signal into two,
[00:22:38] yeah, two sine waves,
[00:22:41] a real signal and an imaginary signal.
[00:22:44] So the thing here, this is the normal sine wave
[00:22:48] and the imaginary signal is the same sine wave
[00:22:50] just rotated by 90 degrees.
[00:22:54] You can see this by using an oscilloscope.
[00:22:58] Maybe I use, can I use this slow, no, what's better.
[00:23:03] Yeah, you can see this maybe here.
[00:23:09] And then we have this one here
[00:23:10] and this is exactly the opposite way.
[00:23:13] Maybe use a trigger to stop the, can I do this here?
[00:23:18] Maybe we need to use a button here.
[00:23:23] It's probably not working in the pitch mode.
[00:23:28] Yeah, this is too fast.
[00:23:30] So the frequency is too high, of course.
[00:23:32] It doesn't matter, but you have to trust me.
[00:23:34] So this is just the same sine wave rotated by 90 degrees.
[00:23:38] Okay, so then we try to bring in here the real signal
[00:23:44] because we just multiply our signal with the real signal
[00:23:53] and we also multiply our signal with the imaginary signal.
[00:23:58] Yeah, that's actually something you have to do.
[00:24:05] You have to trust me on that.
[00:24:07] Then we need the filter
[00:24:09] and it doesn't really matter what kind of filter you use
[00:24:12] but all of these filters have different outcomes
[00:24:15] a little bit.
[00:24:16] So I starting here with the SVF filter.
[00:24:21] We pull down here the pitch and we also go to C3
[00:24:25] and also we pull down here the resonance.
[00:24:27] We filter the first signal
[00:24:29] and we also filter the second signal here
[00:24:34] and then we multiply this again.
[00:24:36] Multiply this, multiply the second signal
[00:24:42] and we multiply this here again with the imaginary signal
[00:24:46] and here at the top also with the real part
[00:24:49] and then we just add this together.
[00:24:53] I showed this in my other video about FFT,
[00:24:56] how to do or very basic.
[00:24:59] It's not really FFT or it's more like DFT in the grid
[00:25:04] and I think I explained it a bit more what I do
[00:25:07] and why I do it.
[00:25:08] Yeah, but here I just want to show you basically
[00:25:11] this is the problem is we have a sine wave
[00:25:16] and the sine wave has a phase, right?
[00:25:18] And then we have also our audio signal
[00:25:20] and the audio signal probably has some frequency content
[00:25:25] at 1K and we just represented of course
[00:25:28] as a sine wave at this position
[00:25:31] but sine wave has a different phase
[00:25:33] and we don't know the phase.
[00:25:34] So we have to figure out basically what is the phase
[00:25:38] of this audio signal of this frequency
[00:25:41] of this audio signal at this position.
[00:25:44] And it's not really possible.
[00:25:45] So what we do here is we use a sine wave
[00:25:47] an ideal sine wave where we know the phase
[00:25:51] and then we rotate the phase by 90 degrees
[00:25:54] and then we figure out how much the signals
[00:25:58] actually canceling each other out
[00:26:01] and dependent on this cancellation
[00:26:04] of how much you cancel something out
[00:26:06] we can figure out how much we are different
[00:26:11] in terms of phase if we are actually
[00:26:13] have a positive or negative phase shift.
[00:26:15] We can make this out basically with the volume
[00:26:18] or with the gain reduction you get
[00:26:19] from the cancellation where you are
[00:26:22] in the position of the phase.
[00:26:23] So this is the idea behind this here, right?
[00:26:26] So we multiply the signal
[00:26:28] and then we get some certain magnitude out of it
[00:26:31] and we can figure out if we actually hit exactly the phase
[00:26:34] of the audio signal or if we are different
[00:26:37] or if we have a difference.
[00:26:39] Okay, so now that we have this here
[00:26:43] we can actually just subtract
[00:26:45] this signal here from our real audio signal.
[00:26:53] So now, let me show you this here
[00:26:57] with an EQ analyzer, EQ curve analyzer.
[00:27:02] This is actually the best part
[00:27:03] or the best way of showing you what's going on.
[00:27:06] So now you can see we have a notch
[00:27:11] or we made a notch filter with this.
[00:27:14] It looks weird but it's exactly like that.
[00:27:18] So we have a sine wave.
[00:27:20] We can change the frequency of the sine wave here
[00:27:22] which changes of course the frequency of the notch.
[00:27:27] So we can say at two kilohertz
[00:27:29] we want to filter something out
[00:27:31] and you can see it's exactly at two kilohertz.
[00:27:34] And then we have here these kind of dips
[00:27:39] or like resonances around the notch frequency.
[00:27:44] And this is what you can change actually
[00:27:47] with the filters here.
[00:27:49] So here's a constant again
[00:27:52] and we use this constant to change the frequency
[00:27:57] of the low pass here, right?
[00:27:58] Turn this all the way up
[00:28:02] and then we go down to zero dot one maybe,
[00:28:05] something like this.
[00:28:06] So the trick here is to use the constant for the filter
[00:28:10] because the filter only goes down to 20 hertz
[00:28:13] which is not low enough.
[00:28:15] We need to go lower maybe to 10 hertz or five hertz.
[00:28:18] And you can do this here with a constant
[00:28:21] going into these modulation inputs here
[00:28:25] and then use very low numbers.
[00:28:27] And you can really filter out a lot of stuff.
[00:28:31] You can see it gets narrower and narrower.
[00:28:35] This kind of notch filter.
[00:28:40] And then here, these kind of bumps,
[00:28:42] these resonant bumps we can remove.
[00:28:44] I found it out by using here a low pass ladder filter
[00:28:48] instead of this SVF.
[00:28:52] And then switch this to 60 B per octave, what is it?
[00:29:03] Yeah, it's the steepness of course.
[00:29:05] Yeah, so we can get rid of these bumps here
[00:29:09] by just using the six option here.
[00:29:12] Then we can make this narrow or wider.
[00:29:17] And also if you want to go down to let's say,
[00:29:21] zero dot zero eight is 80 hertz, right?
[00:29:28] You can see here it's more or less like a low cut
[00:29:33] but we want to have a dip, we want to have a notch.
[00:29:35] So we have to make the filter lower here.
[00:29:39] Yeah, get this kind of dip here at exactly 80 hertz.
[00:29:46] It's perfectly 80 hertz.
[00:29:48] So yeah, this is also a possibility.
[00:29:53] And of course, we can add here certain macros
[00:29:57] to change maybe the frequency.
[00:30:02] Maybe we want to go to 60 kilohertz.
[00:30:05] That's the highest frequency here.
[00:30:07] Then we use an amount or attenuate here
[00:30:12] after the constant and you modulate this.
[00:30:18] Now we can change the frequency.
[00:30:20] It's not perfect.
[00:30:26] We probably want to use also exponential maybe.
[00:30:31] Maybe.
[00:30:32] Yeah, that's better.
[00:30:35] And then you probably want to use or change the constant
[00:30:45] here for lower frequencies differently
[00:30:48] to higher up frequencies.
[00:30:51] So we can use maybe a blend.
[00:30:53] So lower frequencies are here.
[00:31:00] And higher frequencies are maybe not that,
[00:31:05] not that narrow.
[00:31:10] So maybe something like this.
[00:31:12] And then use the amount knob here for the blend.
[00:31:16] So we can change here the low pass filter frequency.
[00:31:21] Yeah, cool.
[00:31:26] If you want to go lower here in volume or in notch,
[00:31:29] like it goes only to minus 60B,
[00:31:31] it's probably because we are not hitting
[00:31:34] the frequency completely right.
[00:31:36] There's maybe an offset.
[00:31:37] So what you can do here is use maybe a gain for that,
[00:31:44] then increase it again a bit more
[00:31:47] and you get more notch, more gain reduction, right?
[00:31:51] Pretty cool, huh?
[00:31:56] And it also kind of rocks here with the sound.
[00:31:59] Yeah, it's maybe not wide enough to hear it perfectly.
[00:32:13] It's always too narrow.
[00:32:15] So let's go down here and maybe make this a bit wider.
[00:32:21] Let's go here, make it a bit wider.
[00:32:26] Okay, let's listen to this.
[00:32:28] Yeah, basically your own notch filter inside of the grid.
[00:32:43] And yeah, this changes the face, sadly.
[00:32:46] So you have some face options here.
[00:32:49] It's not, it's more like an experiment.
[00:32:51] It's probably nothing you want to use
[00:32:53] on an audio track, maybe as an audio effect.
[00:32:57] What you also can do is you can,
[00:33:00] instead of subtracting here the signal
[00:33:02] from the audio signal, you can add it to the signal
[00:33:05] so you get the bump.
[00:33:06] So it's more like an, yeah, peak EQ.
[00:33:11] So you can push certain frequencies here
[00:33:13] by a certain amount.
[00:33:14] Let's try this.
[00:33:19] (drums beating)
[00:33:22] And then you add an attenuate here.
[00:33:32] You can change, oh, not that.
[00:33:35] Yeah, and you can make this to an amount knob.
[00:33:40] (drums beating)
[00:33:49] (drums beating)
[00:33:51] Right, and then you can change how much
[00:33:53] you want to push certain frequencies here.
[00:33:56] So it's basically your own EQ
[00:33:58] in a very complicated way.
[00:34:02] I mean, that's the fun part of PITVIC.
[00:34:05] So this is also a possible way here.
[00:34:08] And then you have to maybe bring here also
[00:34:11] an envelope follower.
[00:34:17] And then you can analyze here the signal, what's going in,
[00:34:20] and then you have to, you know,
[00:34:24] make some changes here for the ratio,
[00:34:26] how much you want to reduce the frequency,
[00:34:28] and then you can modulate your attenuate,
[00:34:30] or the gain, or whatever you want to do, I don't know.
[00:34:33] So this is just a way of creating a very narrow
[00:34:37] notch filter instead of using the basic
[00:34:41] notch filter of PITVIC Studio, or an EQ.
[00:34:45] You can use basically this, so it's very narrow,
[00:34:48] and it's very experimental, and it's very fun.
[00:34:51] So this is my video on resonance suppression,
[00:34:56] or how you can do it in PITVIC with native tools.
[00:35:00] I think the first one is the best one,
[00:35:03] because it's very easy, very straightforward,
[00:35:05] and it just works, but this one is fun too.
[00:35:09] Okay, let me know what you think in the comments down below.
[00:35:12] Give me a like, Merry Christmas, and I hope to see you soon.
[00:35:16] Maybe I do a stream, I don't know, probably not, maybe.
[00:35:20] Okay, thanks for watching, see you next time, bye.
