Hi all.
Please answer me - does iPP include AGC algorithm implementation? If yes - where is it?

Hello Dmytro,
AGC==ALC in IPP (... the automatic level control.)
Could you please take a look upon theippsALC_G169_16s() and uscalc.c file in speech samples for example?
BTW did you try IPP AEC in Voip?
regards,
Ivan

Thank you for clarification. I will try to play with ALC.

AEC - not yet, hope to make some tests later...
