backend.src.libs.fffamily.pyaudioop Namespace Reference

Functions
Iterable[int]	_samples_from_fragment (bytes fragment, int width)
int	rms (bytes fragment, int width)
int	max (bytes fragment, int width)
int	avg (bytes fragment, int width)

Detailed Description

Minimal shim providing a subset of the stdlib `audioop` API.

This file is intended as a temporary compatibility layer for
environments where the C-extension `audioop` is missing (e.g. custom
Python builds or stripped-down containers). It implements a few small
helpers that `pydub` commonly calls: `rms`, `max` and `avg`.

This is a light-weight pure-Python implementation and may be slower
than the C-extension for large buffers; it is only intended to
unblock imports and normal usage of `pydub` in CI/dev containers.
