Hi,
could you please recommend me some audio CODEC with DSP inside running audio processing? My task is to improve intelligibility of communicator on the parking lot. With engine running, it is hard to hear what the driver says. I wish to remove the engine sound from the microphone path. Not by dynamics processing (noise gate), but by selective way. I am not allowed to make any changes to mechanics of the communicator, nor can I charge my software guy to do the signal processing. He is using some 3rd party AEC libraries and he says that there is not enough computing power to add some software noise remover. My idea is to use some part that looks like I2S audio CODEC but has the audio processing DSP with ROM libraries inside. Thanks for tips on parts!
