ReplayGain > write trackgain

Post by j33n7 » Wed Oct 10, 2007 10:42 am

good day!



It would be nice if play wrote the track-gain value also whenever I choose to "scan whole album" - I think this would be easy to do because the values are scanned anyway. this is because I like to choose whether I want to hear shuffeled songs or whole albums from time to time.

regards - jens

Play should always scan track gain when calculating replay gain (album or track). Are you observing different behavior? To see what Play thinks the RG values for a track are, check in the Track Info window under the Replay Gain tab.

I am sorry, you are right! I just tested that, running "scan as album" on a newly added bunch of mp3 files to the library. The track-gain data is stored also.

Rockbox (again!) did not read this data correctly. play does. :oops:

For MP3 files Play writes TXXX frames named replaygain_track_gain and replaygain_album_gain. I don't know if Rockbox reads those frames, or only the LAME header.

TXXX frames means id3v2, right? this would have been my next question. rockbox is able to read id3v2 (.3?) metadata.
It will read foobar replaygain tags, provided they're in ID3v2. APEv2 are current ignored.

If this is the case, then it seems to me that Rockbox should read RG tags written to MP3 files by Play, since Play uses the same format as fb2k (TXXX frames are ID3v2).

what id3v2 tag version is written by Play? can your clear this up - is it id3v2.3 or id3v2.4?

thank you! that is the problem with mp3-tags and rockbox. rockbox only reads id3v2.3 correctly.

Maybe it would be cool to let the user decide which ID3version (.2,.3,.4) is written to the files.
