Feature description

Add support for compressed lossless format - best candidate would be flac

from leaumar

Exposing the compression level or not is up to you, but in my experience the increased compression levels waste a lot of precious cpu time for barely any gain. I googled a reference example for you.

Why do you want this feature?

Compresed - more space available Lossless - no unwanted change
