I need some help figuring out the command-line equivalents to the default GUI settings of album and track gain of mp3gain.

I compiled a version of the CLI back-end for NetBSD, but I get different results when using the -r and -a options:

For example, if I use the default track gain in the GUI (v1.2.2b), I get this result:

MP3GAIN_MINMAX
130,188
MP3GAIN_UNDO
+004,+004,N
REPLAYGAIN_TRACK_GAIN
-0.560000 dB
REPLAYGAIN_TRACK_PEAK
0.520816

On the same mp3 with the CLI (v1.4.3) using -r, I get this result:

MP3GAIN_MINMAX
134,192
REPLAYGAIN_TRACK_GAIN
-6.580000 dB
REPLAYGAIN_TRACK_PEAK
1.041632

The lack of an undo tag is troubling, and I don't see an option in the CLI to enable it. Can anyone help with the correct CLI switches?

Thanks

Strange. I have the same command line version under linux and it writes undo information in both modes, radio and album.

I did a fresh compile and on further experimentation it seems to be working correctly!

So I'll chalk this up to user error or something very odd..

Thanks

It's a moot point now, but my guess is that somehow the -r switch did not actually get turned on, so no changes were made to the file. Thus, no "Undo" tags were written, just analysis results.
