Hello, about the loudspeaker example, so the output of an LTI system is the convolution of the input and impulse response, if we instead want to obtain the impulse response we have to do deconvolution of the output and input? How do we know what input is going to best characterize the system? Why the exponential sine sweep, couldn't it be any other signal and still get quite the same impulse response?
That is exactly my task. But I would like to deconvolve a signal from a drum library recorded in a certain studio B, to get the impuls response of that studios recording room. I have the dry snare or hihat signal from the direct mic and the signal of different room mics. Why? There are other libraries recorded in other smaller studios and if I wanna use a snare from studio A being much smaller, the reverb sounds weird when using it in a mix af studio B. With the IR of the reverb of studio B I can reproduce the room characteristics of studio B and it fits better in the mix. So far the idea. Now I need a software or lots of brain ... and time.
Have I helped you with this video? If yes, please, consider buying me a ☕ coffee at www.buymeacoffee.com/janwilczek
Thanks! 🙂
Thank you so much. This will definitely help me to make some experiments
Thanks for the feedback! And good luck with your projects :)
Tnx man for ur effort and clear explanation
Really insightful video, thanks! Also I have no idea how you managed to say quefrencies and keep a straight face haha. What a funny word
Haha, true! It's the 1970s all over again!
