Hi David,

When you say repeat, do you mean repeat a decode with the last encoded packet 
or just use the previously decoded audio during playback? 

I'm also wondering how strong is the dependency between subsequent encoded 
packets? If there is a discontinuity due to packet loss will the decoder have 
some period of instability or is each encode/decode pair independent?

Thanks for your help,
Marko

Hi Marko,

Just repeat the last (or maybe next) packet.  My tests indicate a PER of 10% to 
be the limit for useful speech quality.
