Title: mp3gain layer I, II and III errors
Post by: paulhar on 2004-04-23 07:49:29
Using mp3gain 1.2.3 [back end 1.4.3] in Windows XP for the first time. I'm trying to adjust the volumes without munging any files but getting a reasonably load consistent album view.

Settings I've chosen: Don't clip when doing Track Gain [don't think it does anything in album mode though]. Default of 89.0Db gain.

When running through my music collection approximately 1000 errors appear.
E.g.
----
23/04/2004 02:28:37    Error while analyzing: F:\music\Hamiroquai\Emergency on planet earth\09-Revolution 1993.mp3 is an MPEG Layer I file, not a layer III file

If you think this is incorrect, you can try enabling the No Check for Layer I or II option
----
All the files are mp3 files but if I take one individually and force it through by disabling the layer check when I listen to the resulting file I notice that artifacts have been added. If I attempt to undo the change the file still has the artifacts, so I suspect is now destroyed. Not a problem; I'm running against a backup of my music.

Question; is there a way of "fixing" my mp3 collection without having to re-rip everything so that files that mp3gain can correctly identify the files as mp3 files?

DBPowerAmp reads the mp3tag for the above error and says: "Xing (old) MPEG 1 layer 3". Other files that have the same error are encoded by Blade,  Xing (new), plus probably others as I've been ripping my collection over many years.

I'd double-check to see if they really are MP3 or MP2/MP1. Try opening them in Encsport or foobar2000 or Winamp and see whether they think it's layer3 or not.

Winamp / Foobar2000 open an play them fine.

Magic! Ran one through the foobar2000 "Fix MP3 header" option and now mp3gain can process them...
