This week, something short. To run tests, I needed a selection of WAV files. Fortunately for me, I’ve got literally thousands of FLAC files lying around on my computer—yes, I listen to music when I code. So I wrote a simple script that randomly chooses a number of file from a directory tree (and not a single directory) and transcode them from FLAC to WAV. Also very fortunately for me, Bash and the various GNU/Linux utilities make writing a script for this rather easy.
