I am working on an audio project and I am looking into using DSP hardware to implement adaptive algorithms for active noise cancellation. I do not have a clue on how to precede on the selection and I dont know what to look for. I know that the A/D + DSP + D/A conversion of the hardware has to be less than 100 microseconds. I have about 3-4 8 bit inputs of audio sampled at 10 kHz and need to output an audio signal.
