Because wav isn't one of these input types, you can't use this feature with music stored in .wav files. You can use it for any other filetype that can be transcoded to wav.

Simon, please accept my apologies for my earlier very poorly worded reply.
I’ll attempt to be succinct with this one.

Are you able to provide a way to invoke ffmpeg with a wav file?
