I would like to build a quick and dirty analysis tool, such that I could sweep a sine wave or perhaps give a quick impulse response to a space and then, using a microphone analyse what the room does to this signal (thus revealing harmonic resonances of the space).
I think maybe the new (and amazing) AudioLab library could be useful for this, and there is the older Pd Spectral Toolkit that allows for working with complex numbers and is amazing, and of course William Brents TimbreID,
but since I don't really need this to do everything that programs like this do: https://www.roomeqwizard.com/
I was trying to think of the simplest way to do this, before I commit to a six month project
I am feeling lazy, it happens.
I wondered if anyone had any suggestions or new of some patches that already did this?
I thought the simplest way might be to sweep a sine wave and simultaneously record it back in, then play this recording into sigmund~
...but here is where it gets confusing because since room sounds are not musical instruments, the most resonant partials are not....well, the whole point is that one doesn't know where they are, so I wouldn't know which partials to tell sigmund~ to analyse ahead of time.
so, it might be better if the recorded sound was played into another spectral analysis tool (but which?) and then the output of this could be filtered to find x number of strong partials (or all partials about a certain strength).
Wouldn't that be awesome?
I am dreaming but maybe somebody has already started on this?
