I was wondering if anything exists or anyone is working on something like this. Basically a DSP that can filter and cancel external noises with phase cancellation. With todays DSP units having the power to pull this off it would be amazing. It could map out the freq response of the cabin, like autotune, then perform a constant on the fly RTA of externally generated noises and run a cancellation algorithm through the signal chain, restoring the audio to how its supposed to sound in a dead environment. basically have a mic feeding it constantly and readjusting the signal on the fly. or am i just crazy.
