dB → Lin

Bitwig Platform

dB → Lin module panel in Bitwig Grid
dB → Lin in Bitwig Grid 6.0.6.

Converts an amplitude value expressed in decibels into a linear gain factor.

What it does

dB → Lin turns logarithmic decibel values into multipliers that can be applied to an audio signal. Zero decibels becomes 1, negative decibels become factors below 1, and positive decibels become factors above 1.

Controls and ports

The wrapper has one decibel-value signal input and one linear-amplitude output. It has no selectable reference or conversion mode.

Practical uses

  • Convert a dB control value before multiplying it with an audio or modulation signal.
  • Translate familiar gain values such as -6.0206 dB into approximately 0.5.
  • Pair it with Lin → dB when a patch needs to move between logarithmic display values and linear DSP values.

Things to know

  • This converts amplitude ratios, not power ratios.
  • A decibel value is not itself an audio gain multiplier until it has been converted.
  • Very large positive dB inputs can overflow the finite floating-point range.

Technical details

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

Standard amplitude conversion: linear = 10^(dB / 20). Reference points are 0 dB → 1, -6.0206 dB → 0.5, and +6.0206 dB → 2. The exact visible wrapper is not mapped in the current Nitro atlas.

Open questions

  • Measure overflow handling for extreme positive dB inputs.

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.
