reduced to 8 when making a call.

c2f14834e5 Rename dbm0 (level) to speech (level)

31fca59294 Fixed performance issue with IIR filter 
Passing samples with zero value (0.0) causes very slow processing of
IIR filter on my test machine 'nuedel'. I don't know why.
To solve this, I add a very small number to each input sample.
