Re: [AVT] Requesting feedback on new CELT codec

["Christian Hoene" <hoene at uni-tuebingen.de>]

Hello Jean-Marc,

Great work! 

I would suggest you to support multiple coding rates (from 16 to 200) and
various coding delays ranging from 2ms (for interactive ensemble
performances) to higher delays (e.g., 40ms if the is beneficial for the
audio quality).

Then, various application scenarios and the use of CELT over congestion
aware transport protocols like DCCP or TCP would make sense.

With best regards,

 Christian Hoene
