From 8f785524ae6309c2bb949537b33146d67d69a149 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?J=C3=B6rg=20M=C3=BCller?= Date: Thu, 19 Aug 2021 22:21:22 +0200 Subject: VSE: Adding a panning angle for multichannel audio. The panning angle allows a more intuitive panning when the output is surround sound. It sets the angle on the horizontal plane around the listener. 0 degrees is to the front, negative values go to the left and positive ones to the right. +/-180 degrees is directly from the back. Technical detail: the panning value is linear with the panning angle with a factor of 90 degrees. For stereo this means that -1 is left and +1 right, since the speakers are exactly 90 degrees to either side.
