Something has occured to me. We have smartphones, smart cars, smart fridges and what do I know, perhaps even smart toilets. But why don't we have smart headphones? Couldn't it be possible to have a smart headphone which would eliminate distortion by playing an inverted signal, a principle similar to the one noise cancelling headphones use? Of course, this would create distortion of its own, but of much lower level, which could then be again eliminated by the same method. You could go on and on until the distortion would be inaudible.
Or take CSD waterfall plots for instance. These measure the speed of sound decay. Couldn't the trick described above be used for increasing decay speed? If you are a reproducing a certain frequency, once you stop and the driver is resetting to its stationary position naturally, wouldn't it be possible to speed this up a bit by playing an inverted signal of a specifically calculated amplitude? Like quite literally taking the driver which is slowly finding its way back to its resting position and forcefully snapping it back in there quickly?
The algorithm could even look forward in the music track being played and evaluate to which extent to the incoming signals help reduce the decay time, and add its own little magic whenever necessary.
Am I completely crazy or do such ideas have some merit?
