I have some songs in wav format. I would like to convert them to flac (which is also lossless, but has compression).
The solution needs to recurse through subdirectories to find .wav or .WAV files (ideally case insensitive), convert them to .flac and output the .flac files to a different directory tree. The original wav files are in ~/Music and the output flac files could go into ~/Music_Flac.
I am using Arch Linux x86_64 and I have ffmpeg as follows:
