I'm using IPP echo canceller/denoiser in our VoIP product and it works quite good with IPP 6.1.2
After linikng with IPP update 4 I noticed that output voice signal volume became much lower if compare
with update 2. When I switched back to 6.1.2 things went back normal. What can be the reason?
Noise reduction mode was changed from Medium to High.Much noise eliminated, and voicesignal power lowered accordingly as well.
