Lossless adjusting of loudness for MP3 and AAC files
Authored by: joshburnett on Sep 07, '05 05:14:09AM

I'm using v1.4 of aacgain, and I've noticed that the '-s d' option doesn't seem to be doing its job. (That's the option to de-AACgain the file) I've created a copy of my original file (appending ' copy' to the file name), then run 'aacgain -r -p -t -k' on the file. In iTunes I can definitely hear the difference. But when I then run 'aacgain -s d' on the file, I still hear the difference in iTunes.

Also, I've used Polonus' script (nice work!) to try this out, with the same results. I run 'AACgain selected files' followed by 'de-AACgain selected files' and there's still a difference between the original and the modified file.

Any idea what's going on here? Yeah, yeah, I've backed everything up, but I'd still like my changes to be reversible, since the program claims it is.
