VorbisGain is a utility that uses a psychoacoustic method to correct
|
|
the volume of an Ogg Vorbis file to a predefined standardized
|
|
loudness.
|
|
|
|
It is meant as a replacement for the normalization that is commonly
|
|
used before encoding. Although normalization will ensure that each
|
|
song has the same peak volume, this unfortunately does not say
|
|
anything about the apparent loudness of the music, with the end
|
|
result being that many normalized files still don't sound equally
|
|
loud. VorbisGain uses psychoacoustics to address this deficiency.
|
|
Moreover, unlike normalization, it's a lossless procedure which
|
|
works by adding tags to the file. Additionally, it will add hints
|
|
that can be used to prevent clipping on playback. It is based upon
|
|
the ReplayGain technology.
|
|
|
|
The end result is that the file ends up with superior playback
|
|
quality compared to a non-VorbisGain'ed file.
|
|
|
|
It needs player support to work. Non-supporting players will play
|
|
back the files without problems, but you'll miss out on the benefits.
