This package provides a Python package to calculate the Replay Gain values of audio files, and store those values in the files as metadata. Media players that support Replay Gain will use this information to adjust the volume during playback, so that all tracks sound equally loud.

Replay Gain is a proposed standard designed to solve the problem of varying volumes across audio files. For more information see .

This library is primarily intended to be used by the replaygain package, and its API is not necessarily stable.
