Speex dev - Oct 2009 - High CPU usage

Hi Jozsef,

this approach sounds interesting.
Do have you have some source code available ?

Thanks

Mark

I have run into the same issue. Before sending a frame to encoder, I calculate
the energy. If it is less than a small threshold, I simply replace this frame
with "silence frame," which is 320 random samples of values smaller
than 3 (16 kHz).

BTW, I have only experience this problem with certain USB headsets that provide
you all 0 samples when muted.

Hi,

I am having a similar problem. Definitely when some head phones are muted I get

high CPU usage. Also it seems on some older machines using Pentium 4 the CPU 
usage is very high. 

Does compiling speex API with DISABLE_FLOAT_API and DISABLE_VBR solve the 
problem?

Thanks
