Hi, I downloaded Ulrich's TestClient and have not been able to connect to the default server. I will try to modify and get to work locally(local echo). I wanted to test my SpeexDecoder as no matter what I try I alwasy get an java.io.StreamCorruptedException: Invalid sideband mode encountered. (2nd sideband): 7 Please note that the Invalid sideband modes differ per file but the end result is always the same - I cannot decod any speex files. I've tried Ogg Speex/Wave Speex encoded by jspeex-v0.9.2_R1.12/speexenc/speexACM-v1.0.1.1 at 8/16/22/32/44 kHz I've spent countless hours before actually asking for help. Do you have any hints on how to solve this problem I downloaded the latest source code from jpeex.sourceforge.net. I have attached the sourcecode. Thanks for your help Andre <p><p><p> -------------- next part -------------- A non-text attachment was scrubbed...
