...t the fact that the packet > loss concealment > hasn't been completely converted to fixed-point. I am using intel x86 CPU. The high CPU utilization go away after I put the following code protection code: // when no packet arrived do the following... if(!m_IsZeroData) { speex_decode_int(decoder_state, NULL, shortData); //check if shortData[] array is zero bytes. m_IsZeroData = IsZeroData(shortData); } m_IsZeroData will be set to false when new voice packet arrive. It seems to me that speex_decode_int() can not be execute too many times after shortData[] become zero. Regards, YueWeng _____...

...l, I am using speex 1.17 at this moment, everything works great. However, I face a problem when no packet arrived from network for a few second, my CPU usage is 100%. I step though my code and seems that (not confirmed) the speaker callback WaveOutCallback() function which call speex_decode_int(decoder_state, NULL, shortData) (when no data arrived for PLC purpose) seems to consume a lot of CPU slice. Is this normal or I am making a mistake other portion of the program. Regards, YueWeng __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

First, in the decoder make sure that you turn perceptual enhancement *on* (it is off by default when using the libspeex API). To do that: int tmp=1; speex_decoder_ctl(decoder_state, SPEEX_SET_ENH, &tmp); For the rest, all you need to do is decide whether you want constant bit-rate or variable bit-rate and whether you want discontinuous transmission (DTX). You might also want to play with the "complexity" value, but the default is usually OK. Jean-Marc...

Hello, the voice-communication TeamSpeak (www.teamspeak.org) is currently testing a version that supports speex codecs. The quality for high bitrates is quite good. BUT, the low-bandwidth speex codecs that are currently used arent very good. What I did to find this out: I comprared a speex AVB with 6.3 KBit/sec (total, overhead for packets and stuff included) and the 6.3 Kbit/sec Celp Codec
