Mammoth Sound Studio (Mammoth Sound Studio) asked a question.

Dolby Atmos Binaraul mix channels are uneven.
I am testing my configuration, and have got an uneven weighting in the binaural render. In the screenshots you'll see I have a Singal Gen being sent to the side channels, and the balance is even between L&R. The signal is also even in my Galaxy 32 control panel (post renderer) and in the renderer itself, but the binaural render is louder on the L channel. The same happens if I use any other channel, for example, the front L/R. Can anyone advise as to why this is? Am I doing something wrong?

    It's correct afaik I don't know why, it must be how the ITD & ILD of the Dolby HRTF works perhaps? Here's off/near/mid/far from Davinci Resolves Binaural Renderer.

      So, I was exploring a little further this morning. When I was using a sine wave in the signal gen. this effect was seen. As I changed the sine's frequency, the imbalance adjusted. White pink noise the binaural balance was fine. I'm sure someone will be able to give me the scientific reason! But I'm glad I found an explanation.

        Yeah you won't see it once mixing music though it. Many other binaural processing plugin do the same, although not all weirdly.

Don't see what you're looking for?
