I'd guess that your script and the mp32ogg script use different -q values with oggenc. Either way, transcoding from one lossy format (mp3) to another lossy format (ogg vorbis) is going to give you bad quality. I wouldn't bother trying to "convert" mp3s into oggs. Your best bet is to do all your new encodings in ogg from the original source, and if you have mp3s for which you don't have the original uncompressed source, just hang onto the mp3s. Of course, for certain audio files (speeches, etc.) the sound quality may not be that important, and the reduction in quality might not even be noticeable. But if you want decent quality music, fuggetaboutit. good times, Vineet -- http://www.doorstop.net/ -- http://www.digitalconsumer.org/
