Creating Realistic Rain Sounds in Bitwig

Tutorial | Jan 30, 2023

I was creating a dense rain sound effect by layering different noise modules and then changing the volume of the noise with a multiplier. I then added layers to the sound with a sample and hold, a bandpass filter, and a convolution with a room. Finally, I modulated the EQ to change over time.

Whats the best way to create rain?

The best way to create rain is to use two noise modules to create stereo white noise, then use a multiply to modulate the noise and add a volume slider. You can also add some layers with ADSR envelopes, band-pass filters, and convolution to create a more realistic sound. Finally, you can modulate the filters over time to create a more dynamic sound.


If you don't want to watch the Video, or search for a specific topic, here is the transcription of the video with links to video markers:

[00:00.000] So you just take noise
[00:06.760] and maybe a volume slider here.
[00:10.400] So this gives you basically just white noise,
[00:17.440] stereo white noise.
[00:19.760] And then you can take a multiply,
[00:23.600] just multiply the same noise here with this
[00:28.320] and also with the volume in there.
[00:53.680] This is basically dense,
[00:54.960] dense, heavy rain kind of.
[01:00.080] At least sounds like this way.
[01:01.920] Need of course a bit of EQing.
[01:16.320] Put the dates in the preset names.
[01:17.920] Yeah, but it's always a hassle to find out the current date and type it in.
[01:34.960] Up is at the end, yeah.
[01:39.760] Let's use the label.
[01:40.800] So this is dense rain.
[01:50.320] I think why it works is that when you use your two noise modules,
[01:56.880] these have different seats and I think that's why it works.
[02:02.320] And then when you use pink noise here
[02:04.080] and then modulate basically pink noise with the multiply,
[02:07.520] you change the volume on different amounts.
[02:11.840] So it sounds like a bit fizzled out.
[02:25.760] So this is dense rain.
[02:27.360] And then you have to add some layers to it,
[02:29.280] of course, because it's on its own.
[02:32.240] It's a bit boring maybe or maybe it's exactly what you need.
[02:43.120] Then you can do something with ADs or with an envelope at least.
[02:52.480] And you trigger this one here also with noise.
[02:54.720] And because only everything above 0.5,
[03:07.440] so when you look at the noise, right, you have this signal here.
[03:13.360] So you can increase the loudness then.
[03:15.840] And everything that passes here 0.5 is a trigger.
[03:20.000] So when you find you at the sweet spot where some of these noise bits go over the line,
[03:28.080] then you trigger basically the AD.
[03:29.840] And you get something like this.
[03:41.280] So it's also nice for creating a windmill brackle probably.
[03:59.680] Also need some filtering here.
[04:01.040] So this is something you would probably use for.
[04:25.840] Can you slow down the noise?
[04:27.120] Not really, but what you can do is you can use a sample and hold here
[04:38.240] after search for random.
[04:40.240] This one here.
[04:42.720] So this basically also generates noise in a way.
[04:46.080] When you take this output basically and go up here to kilohertz,
[04:59.360] then you can slow down the noise.
[05:02.720] So it's basically also just noise here.
[05:04.880] It's a sample and hold, or it's a sample and holds noise.
[05:22.880] And then we can create some drops here.
[05:30.160] Let's see, some noise.
[05:38.720] There we are.
[05:42.080] And we do basically the same thing as here.
[05:50.000] Relative, so we can change this.
[05:51.920] And then we can use an bandpass filter here.
[06:07.600] Maybe I use...
[06:18.800] Let's use a second one.
[06:49.760] So you get some drops there.
[06:53.280] Of course we have to modulate this.
[07:01.760] Dice.
[07:06.160] So we can even bring in now a chance here.
[07:09.280] To reduce drops a bit more.
[07:18.240] So every time we trigger a drop, we want to trigger a dice and then modulate here the frequency.
[07:38.000] And we find here a nice range.
[07:51.120] So this is what we want to change.
[08:14.320] We also want to change a bit here the modulation amount.
[08:23.840] And also the envelope and then we have to
[08:52.000] find probably some kind of room.
[09:22.000] Yeah, it's always hard to find the right settings for everything.
[09:52.000] Convolution and maybe select a room here.
[10:22.000] And a bit of a cure.
[11:22.000] Yeah, with the resonances too much then you get this.
[11:52.880] Write these tones.
[11:54.880] So we need to find the sweet spot there.
[12:25.280] And then we have to find a nice EQ setting here for the track.
[12:31.600] That fits the track.
[12:43.600] Yes, it would be nice if actually the EQ would change over time because the rain is not constant
[12:49.280] in the real world, right? Sometimes it rains more and then it rains less and so on.
[12:56.400] Maybe I'll modulate a bit for you.
[13:56.720] What a high pass here.
[14:09.520] Okay.
[14:39.520] We can even modify the macro.
[15:09.520] Would be probably nice also to modulate here the filters over time.
