To a degree, this can be -what the artist or producer intended, at least when comparing songs from the -same CD. However, when (randomly) listening to songs from different CDs, the -sound level can vary quite much, so much that you need to adjust the volume -every now and then, to get a comfortable sound level. Wouldn't it be nice if -that could be handled automatically? - -This is where VorbisGain comes in. It calculates a percieved sound level of -an Ogg Vorbis file using the ReplayGain algorithm. VorbisGain then stores in -the comments (tags) in the file a suggestion on how the volume should be -changed during playback, to get a uniform sound level. However, this only -solves half the problem; the player application needs to act on that -suggestion for it to be any useful. +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. + +WWW: http://sjeng.org/vorbisgain.html |
