RE: Feedback removal in Software - An Idea! - An Improvement



Thinking about it some more, you could do it effectively without having to
deal with Doppler.

If you did the DSP on the way Up, and did the subtraction on the RX audio
out and the Mic (TX) audio in. Then only the difference would be sent to the
bird, i.e. the operators voice.

RX Audio Out A
Operators Voice B
Mic picks up A+B
DSP filter does A+B - A
So only B sent to bird, hence no feedback, and all without recording or
Doppler correction
