In an application, I have to handle up to two hands-free stations talking with each other.
Is there an example PPS flow for the AIC3254 implementing a voice switched speakerphone circuit, i.e. a voice-activity controlled attenuation of one direction?
For reference, this is what I'm talking about: http://en.wikipedia.org/wiki/Acoustic_echo_suppressor
Essentially I'd like to mimic the (discontinued) Atmel U4082B (http://media.digikey.com/pdf/Data%20Sheets/Atmel%20PDFs/U4082B.pdf).
Thanks in advance,
Andreas
