Title: Has something changed in the ID3v2 standard lately?
Post by: Matt_H on June 19, 2007, 03:07:06 AM
MP3 files I've downloaded recently all show up as garbage in my Amplifier playlist. Amplifier could nver edit ID3v2 tags, but it could display them correctly in the past. Has the standard changed so that Amplifier now chokes completely on them, or might there be something wrong with my setup?

Unlikely. Not in plain MP3 files. They play fine, it's just the titles that get trashed.

You might be on to something there.  I played a playlist which would lock up my amp and the entire system, until >I figured out it was a particular mp3 file, which I naturally delated.

I have noticed too, that some of the new mp3 song names show up as garbage in Amplifier's playlist.

I think that Amplifier's playlist can't show ID3v2 tags, but then if mp3 has both v2 and v1 tags, then information in v1 is been shown. Sometimes both artist and song names are mess, but sometimes only other one. Have people stopped adding v1 tags? But I'm just guessing... should do some researching :)

ID3v2 support is a bit of a mess to implement.

You can try opening up the file in a hex editor and check if the first three bits are "ID3".  That's where most simple ID3v2 readers would look, but the tag can be located elsewhere in the file.

v1 data is stored at the end of the file in the last 128 bytes.  Look for the word "TAG" 128 bytes from the end of the file.  If it's not there or in the wrong spot that may be it.

Most likely.

Yeah.. it seems that Amplifier understands both v1 and v2, but there's probably unicode crap on those which don't work. They seem to have unicode on v2 tag, but plain ascii on v1 tag... but Amplifier prefers v2 if it's found.

Broken names contain ÿþ before the actual name and on playlist only that ÿþ and first char of the name is shown :)

Maybe there's program to batch strip v2 tags easily?-)
