CLI program for generating audio files
Supported commands:
saw,sine,square,triangle
Generate a waveform with a specified duration and frequency. Duration can be specified in hours, minutes or seconds, or as a number of beats and a tempo in BPM. For example:
Generate 5 seconds of saw wave:
mkaudio saw --frequency 440 --duration 5s sound.wav
Generate a sine wave lasting 4 beats at 120bpm (i.e. 2 seconds):
mkaudio sine --frequency 440 --beats 4 --tempo 120 sound.wav
Generate a square wave lasting half a minute:
mkaudio square --frequency 440 --duration 0.5m sound.wav
white-noise
Duration is specified in the same way as for waveforms, e.g. to generate 10 seconds of white noise:
mkaudio white-noise --duration 10s sound.wav
beat
Generate a simple beat from kick, snare and hi-hat patterns. Patterns are
specified as strings; each character which is 1 or x corresponds to a drum
hit; any other character corresponds to a lack of drum hit. Each character
represents one sixteenth note at the specified tempo. The --repeats parameter
allows generation of longer beats without typing in long repetitive patterns.
8 beats of eighth note hihats:
mkaudio beat --hihat 10 --repeats 16 --tempo 120 sound.wav
A simple syncopated beat lasting 4 beats:
mkaudio beat \
--kick 1001000100100000 \
--snare 0000100000001000 \
--hihat 1111111111111111 \
--tempo 120 sound.wav
