You have been a HUGE help!! I downloaded the sox src files from sox.sourceforge.net. Then i downloaded the src files for the mp3 lib's (from their website). Compiled and installed them both. Then ran a ./configure for the sox app; it's ./configure script did report mp3 support. However, it did not report ogg vorbis support. I then double-checked (using yast) that i DO have the libvorbis file installed (and anything with ogg installed) but the ./configure script reports no support for vorbis. Oh well...I then did make; then su (passowrd) and make install. SoX is installed in /usr/local/bin, yipppeee
I then tried "sox *.mp3 bigfile.mp3" at the command-line...this gives me a bash error: command not found. So i run /usr/local/bin/sox *.mp3 bigfile.mp3 ...it just sits there for 15 minutes, just sits there. I checked the folder and there is a bigfile.mp3 file there, 0kb in size. Not sure what i am doing wrong? Thanks again for all your help!
