Audio Normalization

Description

Audio normalization of a tensor in-place. The normalization can be a bool, a number, or a function that takes the audio tensor as an input. SoX uses 32-bit signed integers internally, thus bool normalizes based on that assumption.

Usage

internal__normalize_audio(signal, normalization = TRUE)

Arguments

signal

(Tensor): waveform

normalization

(bool, int or function): Optional normalization. If boolean TRUE, then output is divided by 2^31. Assuming the input is signed 32-bit audio, this normalizes to [-1, 1]. If numeric, then output is divided by that number. If function, then the output is passed as a paramete to the given function, then the output is divided by the result. (Default: TRUE)
