Option to record audio only

[MaxHillebrand]

[I think] by default you record the mp4. This is often useful and alright.
But in many cases, I only want to have mp3 audio only - it would maybe reduce computation, storage and bandwidth.
Would be cool to have a toggle option of what format to record. [Maybe also support .wav etc]

This would definitely be doable, and yes it would reduce the system requirements needed to run the Talked server. An option to choose the format would be great. I currently allow you to specify the audio codec used for the recording, but it would need a bit more work to properly support audio only.

I think at the minimum an option to choose between a lossy and lossless codec would be good, but I doubt it's going to be a lot more work to implement a generic way to specify it as long as it's configured in the Talked server config.

Thank you so much @mwalbeck!
