九与玖与 : Pan Law是单声道Pan左Pan右时,音量会升高
Technical Editor Hugh Robjohns replies: Some mixer and DAW pan controls work by attenuating the level of both left and right output channels as the pan control is moved towards the centre.
Others work by raising the level of one channel as the pan moves towards that side.
The two fundamental panning laws relate to the way the material will be auditioned. If you want the panned sound to be perceived, acoustically, as remaining at a constant volume regardless of the pan position, then
the centre attenuation needs to be 3dB.
However, if you want the panned sound to be perceived as having a constant level when summed to mono,
the centre attenuation needs to be 6dB
