Does the impulseResponseMeasurer generate an audible sound?
on my MAC it does not, so I simply do not understand how it can generate the system impulse response, what am I missing?
thank you

Hi Mehmet, if you prefer an entirely programatic approach, have a look at sweeptone, mls and impzest. You can use audioPlayerRecorder to play and record the response, or copy the excitation to a playback device and record the response however you want.

Yes, sound is output on the selected device and channel. If there is a loudspeaker connected to that device, it will play. But if you try for example a loopback (just a cable), then you can make a measurement without hearing it play.
