pipeline music generator
Clone this and just run make.
Robotonic takes 4 bytes from stdin on each iteration and generates sound pattern using them as parameters: frequency, wave type (triangle, square, sin or saw), LFO wave type (no LFO, normal fade-in, parabolic fade-in or parabolic fade-out), interval and offset from the beginning of the pattern. Each new pattern overlaps the previous which makes illusion of continuity.
cat $file|./robotonic|$player
, where $file is, f. e., /dev/urandom or anything else you want to playback, $player is any program able to read raw sound data from the stdin and direct them to speakers or maybe even to sound file (f. e., aplay).
Change constants near the top of source file and then recompile the program
- BUF_SIZE — number of samples generated for each pattern
- SAMP_LENGTH — length of samples (shorter is glitchier because this does not affect the frequency)
- RATE — output sampling rate
- NOISE_LEVEL — from 0 to 255, sets the volume of the noise mixed up with the generated sound
