[LAU] OT: Combining a LOT of files

hello everyone, I have a directory full of wav files in folders. Inside each folder, I have wav files, all with unique names, grouped into 2 files, one for each channel. For example: dir_1/ hello-L.wav hello-R.wav alice-L.wav alice-R.wav dir_2/ bye-L.wav bye-R.wav bob-L.wav bob-R.wav dir_3/ etc... I know I can use sox to merge 2 audio files into a stereo mix, like so: sox -M left.wav right.wav output.wav I would love to write a script that will descend into each directory, find 2 commonly named files, assume one is left channel and one is right, combine them, and carry on. While I am familiar with bash scripting, this task is far beyond what I am able to do. Does anyone have any tips, tricks or suggestions as to how to approach this? I suspect the answer will be, "use a programming language," and I wouldn't fault anyone for saying that. Unfortunately I have a hammer made of bash, so everything is a nail. :) (That being said, if you *know* how to do this in, say, python, please tell me and I'll work until I can fill in the rest of the details - I don't mind doing the homework, I just need a map!) Thank you! Josh
