Padding

Added in v0.23.0

Apply padding to the audio signal - take a fraction of the end or the start of the audio and replace that part with padding. This can be useful for preparing ML models with constant input length for padded inputs.

Default: 0.7. Maximum fraction of the signal duration to be padded

pad_section: str • choices: "start", "end"

Default: "end". Which part of the signal should be replaced with padding

p: float • range: [0.0, 1.0]

Default: 0.5. The probability of applying this transform.
