While trying to balance my orchestral template I bumped into something odd which I don’t understand.
Start with an empty project. Add a stereo audio track. Insert the included Test Tone Generator with the default settings (sine wave, -12db). Duplicate the track three times, for a total of four tracks playing the same test tone together.
The level I get at the output varies widely when I mute some of the tracks. Here’s what I get when each track is active (i.e. unmuted):
1 -12 1+2 -11,2 1+2+3 -7,8 1+2+3+4 -4,8 2+3+4 -5,2 3+4 -10 4 -12 1+4 -6,3 1+3+4 -7,5 1+2+4 -5,8
Also, note that when going from 1+4 to 1+2+4 I actually get a lower output level.
Could someone please explain what is happening here?
