I have a folder structure like this:
-dir1 -subdir1 -subdir2 -file1.wav -file2.wav -dir2 -etc...
Inside the folders are thousands of audio files that need to be converted. How can I convert them all at once to mp3? I would like to use the same filenames and keep them in the same folders. The end result would like this:
-dir1 -subdir1 -subdir2 -file1.wav -file1.mp3 -file2.wav -file2.mp3
