Generators
Generators
Plug-ins that create new audio rather than change audio you already have.
A generator writes audio from nothing — a tone, a noise, a rhythm, a plucked string, or an exactly flat stretch of silence. Generators are how you make test signals, tuning references, click tracks and timing gaps without recording anything.
Where to find them
The Generate menu.
How generation works
Generation starts at the beginning of the selection, or at the cursor if nothing is selected. Most generators ask for a duration and write that much audio from that point.
Notes
Some generators are built into Audacity and some are Nyquist plug-ins; they sit together in the same menu.
- Chirp Generate a tone that sweeps between two frequencies and two amplitudes.
- DTMF Tones Generate the dual-tone signalling sounds a telephone keypad makes.
- Noise Generate white, pink or Brownian noise.
- Tone Generate a steady tone at a fixed frequency and waveform.
- Pluck Generate a plucked-string note at a chosen MIDI pitch.
- Rhythm track Generate a click or metronome track at a set tempo, time signature and length.
- Risset Drum Generate a synthesised drum tone built from inharmonic partials and a noise band.
- Silence Generate a stretch of silence of a set length.
