  • @fadeincurve [int/float]: fade-in curve amount, between -1 and 1. (default: -0.25).
  • @fadeoutcurve [int/float]: fade-out curve amount, between -1 and 1. (default: 0.25).
  • @timeunit [int]: time unit for @start and @end. (default: 0).
    • 0: milliseconds
    • 1: samples

Output​

fade operation [llll]

Usage​

fade is meant to be used with the process function:

$buffer = importaudio('singing.wav'); ## input buffer
$op = fade(@fadein 2000 @fadeout 2000); ## processing operation
$buffer = $buffer.process($op); ## apply processing
$buffer.inspect('after fade process')
