trim​

trim(
    @threshold 0.01
    @ampunit 0
    @start 1
    @end 1
) -> llll

Generates an audio process operation for applying silence-based trimming to a buffer. When the entire buffer is considered silent, the resulting buffer's duration will be a single audio sample.

Arguments​

  • @threshold [int/float]: Amplitude threshold at/below which samples are considered silence. (default: 0.01).
  • @ampunit [int]: Amplitude unit for @threshold. (default: 0).
    • 0: Linear
    • 1: Decibels
  • @start [int/float]: Trim the beginning of the buffer. (default: 1).
    • 0: Off
    • 1: On
  • @end [int/float]: Trim the end of the buffer. (default: 1).
    • 0: Off
    • 1: On

Output​

Join operation [llll]

Usage​

trim is meant to be used with the process function:

$buffer = importaudio('singing.wav'); ## input buffer
$op = trim(); ## processing operation
$buffer = $buffer.process($op); ## apply processing
$buffer.view('after trim process')
