waveshape(
    @phase -1 1
    @duration 1000
) -> llll

Generates an audio process operation for waveshaping a buffer.

---

Arguments

• @phase [int/float]: buffer phase envelope between -1 and 1, either as an envelope or a buffer. (default: -1 1).
• @duration [int]: envelope duration in milliseconds. Ignored if @phase is a buffer. (default: 1000).

Output

waveshape operation [llll]

Usage

waveshape is meant to be used with the process function:

$buffer = importaudio('singing.wav'); ## input buffer
$op = waveshape(@phase for $x in 0...90 collect [$x xrand(-1, 1) xrand(-0.25, 0.25)] @duration 3000); ## processing operation
$buffer = $buffer.process($op); ## apply processing
$buffer.inspect('after waveshape process')
