Channel Balance Correction #36

Closed rpx91 closed 5 years ago

rpx91 commented 5 years ago

As requested on Headfi.

Issue: channel balance due to binural mic placement with my Sound Professional mics.

Is there a way we can ask Impulcifer to assume channel balance with the headphones and then attenuate L or R to get balance?

When I correct for it via HeSuVi's attenuation I'm hard pressed to find anything "wrong" with the sound. It sounds really good and is bang on center then. Again I A vs B against the real speakers and they're remarkably similar. It's not identical though, but even my naturally perfect measurement wasn't identical.

I tested the solution to this. Really good - the graph output is very useful.

I found the easiest way to get the channel balance bang on is the 7.1.4 test files for Atmos. Just use the white noise on the center channel and adjust until it's balanced.
