Let's assume a distributed ensemble performance over the Internet using the anticipated IETF audio codec. 

Distributed ensemble performance require an acoustic one-way delay of 25 ms instead of maybe 150 ms in case of VoIP. Thus, also the frame size must be small, say 5% of the RTT. 

Also, the coding rate would be 128kbps for high quality music. Then, we send every 2.5ms a RTP packet having a size of 320bytes plus headers.

Thus, maybe instead of 10 ms, a TFRC-SP Min Interval of min(10ms,RTT/20) would be reasonable?

With best regards,

 Christian
