well, I have a portable microphone and the main source of noise a TV, which is a few meters behind my back, if i put a microphone (for example) in the middle, between a laptop and a TV, it may be possible to compensate for the delay, I repeat, this is all solely for the sake of experiment. вс, 7 февр. 2021 г. в 16:45, Greg KH <greg@xxxxxxxxx>: > > On Sun, Feb 07, 2021 at 04:38:08PM +0300, Ivan Riabtsov wrote: > > I want to experiment with active noise cancellation, i want to receive > > a wave from an input device (microphone), invert the wave and send it > > to the output device (headphone or speaker).
