[Speex-dev] Noise suppression less than AGC gain

[Thorvald Natvig]

Hi,

I've had a small case with noise suppression and AGC. I have a fairly 
noisy environment here, and with the default parameters, noise 
suppression works fairly well while I talk. However, when I shut up, AGC 
starts slowly increasing the gain until it has amplified whatever noise 
is left to levels about equal to having no filtering at all. As soon as 
I talk, AGC backs down fairly quick and the noise is again gone.

Decreasing the AGC max gain and increasing the ammount of noise 
suppression fixed things, but it might be an idea to change the defaults 
slightly?
