Impulse Response Measurer in audio toolbox

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 Joseph,

you can actually export the impulse response as .wav file.

Or are you looking for your played and recorded signal to calculate the impulse response yourself? They are stored as vector/matrix in the irdata_xxx table, which you will export in your workspace or save as .mat file.

I have been working on this topic for the last few days because i wanted to write my own script to generate the impulse response of a room. If the topic is still relevant or you need help, you are welcome to contact me.

Greetings,

Mehmet

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.
