My mp3 was 128Mb, and Audacity filled my /tmp with 3Gb of au files! I found mp3splt, and using XMMS to get times, I am able to chop the files into managable chunks, and it can handle the variable bit rate sampling in the file, creating nice new ones that are much smaller, while preserving the source file. Now, only if I can keep Audacity from crashing. I guess its time to chop some more. Rob -- Linux: For the people, by the people. Want to buy your Pack or Services from MandrakeSoft?

Re: [expert] Streaming MP3-wav conversion problem
This is a script I use for batch conversion; works on one or more mp3's. If this doesn't work, maybe there is a problem with the xmms plugin you mentioned? #!/bin/bash # allmp3wav for i in *.mp3; do echo $i tgt=$(echo $i | sed -e s/mp3/wav/) mpg123 -b 1 -s -r 44100 $i | sox -t raw -r 44100 -s -w -c2 - $tgt done mike I am trying to convert a streaming MP3 file to a wav file for editing in Audacity.
