gainFromiTunesNormalization() [1/2]

float Media::Metadata::gainFromiTunesNormalization ( const char *  value )

static

Get the iTunes normalization, a/k/a sound check.

Parameters

value

The value from the iTunNORM ID3 comment.

Returns

The gain specified by iTunNORM.

getFileGain()

float Media::Metadata::getFileGain ( const std::string &  filename )

static

Get a file's gain for playback.

This is currently done only if:

• taglib is compiled in.
• ffmpeg is the media engine. AVFoundation does this itself; taglib only improves over ffmpeg when there is iTunes normalization and not replay gain in the file's metadata.
