Speex dev - Sep 2009 - High CPU usage

Hi,

I have a curious problem with speex. As long as I'm talking, it takes about
2-5% of my CPU. This seems ok.
But as soon as I stop talking, CPU utilization rises to about 30-45% and stays
there until I start talking again.

I compiled speex from source and use it with these settings:
- Preprocessor: Denoiser = ON, AGC = ON
- Encoder: ABR = 15000, DTX = 1, Mode = narrowband, Rate = 8000 Hz.

My platform: Windows XP SP3, MSVS 2008 SP1, 1.8 GHz Core Duo CPU, 2 GB RAM.

Thanks for your help :-)
Mark

Hi,

Sound like it could be the good old denormalised float problem on the
Intel chips. Just to make sure, can you try compiling in fixed-point
(FIXED_POINT) and see if the problem goes away (it's not a fix, just a
test)? If that's the case, there's probably a few VERY_SMALL's to
add to
some signals.

Cheers,

	Jean-Marc
