I write another voice relay and i use java speex. whenever a new user 
connects to a channel on the relay i transmit the header and after that 
i transmit the live speex encoded channel data. i am right now just 
splitting the header from the content to do the initialization of 
SpeexDecoder the manual way.

however i am not that sure if i shouldn't (for easiness' sake) tweak 
org.xiph.speek to open the audio output line straight away by 
implementing another class based on PcmWaveWriter .... that way i don't 
have to split header from content ...

do you have some hints?
thanks for replying so fast
