I think most speaker setups have a microphone that you place where the listener is to calibrate. Don't know if that involves delay measurements.

- jacquesm 5y agoThere was the Philips concept called MFB which integrated an accelerometer into the low frequency speakers in order to match the desired waveform with the one that actually went out. Quite a neat little concept, they are still somewhat popular in the HiFi scene. The microphone systems mostly calibrate for frequency loss across the spectrum, time-of-flight adjustments I haven't seen but it's quite possible they're out there somewhere, but they would require a pretty nifty delay mechanism or a digitization step and then turning the signal yet again back into analog which would probably cause more problems than it solved.
