Generators
Noise
Generate white, pink or Brownian noise.
Noise fills the selection with random audio of a chosen spectral colour. It is used for testing and measurement, for masking, and as raw material for synthesised percussion and wind or sea effects.
Where to find it
Generate → Noise.
Controls
- Type — White, Pink or Brownian.
- Amplitude (0-1) — the level, where 1 is full scale. Default 0.8.
- Duration — how much audio to generate, entered as a timecode.
Notes
The three types differ in how their energy is spread across the spectrum. White noise has equal power at every frequency and sounds bright and hissy. Pink noise has equal power per octave, which is closer to how we hear, and sounds more balanced. Brownian noise — also called red or brown — rolls off fastest towards the top and sounds like a deep rumble.
Generation starts at the beginning of the selection, or at the cursor if nothing is selected, and runs for the duration you set. The duration has to be greater than zero before the effect can be applied.
