Hi: firstly Greg, FTP directories sort alphabetically. therefore, beta11 and beta12 are going to be before beta2. As for splitting the channels off a wave file, you can do this with the agc effect. If memory serves, the syntax is: sox <infile> <outfile> agc -l (or -r) for more info check out the sox manpage. You can also use arecord in the 0.9x series to record each channel to a seperate file, using the -I switch (I think). I've not used this though.
