Gain - dB

Bitwig Platform

Gain - dB module panel in Bitwig Grid
Gain - dB in Bitwig Grid 6.0.6.

A direct decibel gain stage for boosting or cutting an incoming signal.

What it does

Gain - dB converts its Amount from decibels into a linear multiplier and applies it to the incoming signal. It is useful when exact gain changes matter, because decibel values combine by addition and correspond naturally to audio level ratios.

Practical uses

  • Trim oscillator or effect levels by a known number of decibels before summing them.
  • Create calibrated gain staging around nonlinear processors or feedback networks.
  • Place a low Gain - dB before temporary monitoring probes to avoid unexpectedly loud test signals.

Things to know

  • 0 dB is unity; +6.02 dB is approximately twice the amplitude; -6.02 dB is approximately half.
  • Gain alone does not clip, compress, or protect downstream headroom.
  • A decibel gain is logarithmic even though the signal multiplication itself is linear.
  • The exact visible range, negative-infinity endpoint, and smoothing are not represented by a recovered Nitro wrapper.

Technical details

No Nitro implementation has been confirmed for this visible module. The behavior is described conservatively from module metadata and editorial research.

The standard amplitude-gain equation is out = in * 10^(dB/20). This is the function implied by Bitwig's decibel scaling description, but no dedicated Grid Nitro implementation has been identified. The live pass should confirm endpoint handling, precision, and whether the parameter is smoothed before multiplication.

Open questions

  • Measure minimum, maximum, default, resolution, negative infinity, typed values, and modulation range.
  • Verify -6.0206, 0, +6.0206, -20, and +20 dB against calculated linear ratios.
  • Test smoothing, stereo independence, overflow, non-finite values, and voice scope.

Version and sources

Checked against Bitwig Studio 6.0.6. This page combines Bitwig's module metadata, the existing Grid course and guides, and Nitro analysis where the mapping is strong enough to support a technical statement.
