Full Version: wavgain question
since i'm using mp3gain practically all the time now, i was wondering, can wavgain normalize wav files "loselessly"?
Umm, no. The "lossless" part in replaygain calculations refer to the fact that applying it doesn't need re-encoding. In addition it refers to the reversible nature of the process.
However, wavegain is not losslessly reversible. Even if you remember the exact amount of the gain applied, and apply then the exact opposite gain, the result most probably has some rounding differencies compared to the original.

JohnV is technically absolutely right. However, whether, or not, you can discern the difference is another question.

Where can I get the last version of wavgain's source? Note that most software do not dither the
output properly and introduces a lot of distortions when audio has low amplitude.
10 times replaygained and you have a SNR of
a Top Compact Cassette Tape Deck, but the deck
has less problems with low level distortions.
All in all it's always a bad idea to process
original data directly.
