This is one of the two hardest things to add to FATE ATM: floating point
encoders (for ex. AAC) and network protocols. I'd say that for float
encoders doing encode-decode-compare_PSNR is better than nothing. For
the network protocols, we will need to cook up some session
player/recorder, which looks a bit more tricky. Suggestions are welcome.
