hey there! there was a discussion over at apfeltalk.de about MAX vs. itunes and it came to me that another implemention of a freely available ripping-engine could easy be done (dont't know though). there is a project called rubyripper (: http://wiki.hydrogenaudio.org/index.php?title=Rubyripper ) whi...

thank you very much for this!

hello again!

do you have any plans regarding the location of the mata data atoms within the files?

I recently was looking for a nice way to provide my m4a files with ReplayGain information under Mac OS X and finally found "Play" http://sbooth.org/Play/ which is able to scan and write RG values to mp4 files. I did that and noticed that Rockbox is not able to read any tags from those files. The sa...

0.2 has those changes as well. =) Okay.. here's what I did. I took an album encoded in AAC LC and wrapped into an mp4-container with the extension *.m4a, removed all tags with fb2k and retagged them with foobar and freedb's information. I then let Play (0.2) determine and write RG values to those f...

okay, I'll have to wait for the unstable version then.

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

Thanks for the effort! I've just checked the mp4 files processed by latest Play (r986) and fb2k and Rockbox apparently doesn't read the RG data. I am really stuck here because I cannot find any information on how foobar's tagger works (that is what library foobar uses to write tags) or what tags are...

sbooth, sorry to raise this again but could you post a reply to this topic as soon as you get information regarding your research? I am eager for this!

thanks very much and best regards!

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

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

yeah - maybe there is another problem related to rockbox
I hate standards!

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 ...

This is Play's fault- although it can calculate RG values for any of the formats it supports, not all of them are written back to the original file. m4a is one of the formats that Play cannot (yet) read or write RG for. I'm not actually sure if there is a standard for how RG information is stored i...

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.
