Looked into this one time. You can use your own head for binaural recording, and a small diaphragm condenser microphone at each pinna. Never done it, but many have done it discreetly at concerts. It's a head-fi thing though unfortunately. https://sound.stackexchange.com/questio ... -situation They say earbuds are best to listen on, but I can never get the frequency response just right with them - probably due to proximity always changing and sealing issues - infernal things.Strange Kevin wrote: ↑Wed Nov 13, 2019 4:59 pm I've always wanted to set one of these up at FOH or somewhere in the crowd to see if it actually sounds like I remember... https://3diosound.com/products/free-spa ... microphone
It's not exactly what they are marketed for, but if it worked, It would be a pretty easy way to capture the show.
You can listen with a stereo speaker set-up but crosstalk has to be eliminated, by attenuating, inverting and delaying the opposite channel signal so it cancels out the signal that arrives in the wrong ear (which is the same effect as your head in-between your ears for sound direction sensation).
