information

The signal is lowered as it pans from left (or right) to center using a straight line from (+-)1 (left or right) to 0.0 (center) for a 6dB reduction in the middle. A problem inherent to linear panning is that the perceived volume of the signal drops in the middle. [pan.sqrt~] solves this by taking the square root of the linear scaling factor going from 1 (left or right) to 0.5.sqrt (~=0.707) in the center, which is about 3dB reduction. This is equal power panning. [pan.lin~] sounds more like the Rhodes tremolo than [pan.sqrt~].
