Hi all-
Let's say I want to see a FFT of the signal being picked up by a microphone. And let's say I want to do this in real-time or nearly real-time. I want to see changes as I move the microphone around.
How would you do this? Especially, how would you best do this given constraints on cost and size?
I know you could always use some vintage piece like a spectrum analyzer, fed with the amplified signal from the microphone. But is there a more modern, smaller, less expensive way to do this?
Thanks.
