Yes, I don't have the knowledge myself, but for Qtractor this does a good job. Don't trust my shot in the dark: Alternating voltage is switching between 0 and it's max., hence it's higher, but the nominal voltage by the factor of 1.41, perhaps it has to do with this issue. > > On Nov 11, 2010, at 9:40 PM, Ralf Mardorf wrote: > > > > In January Rui at Qtractor devel-list wrote: > > > > stereo panning in qtractor follows an "approximated equal-power" > > trigonometric formula: L = SQRT2 * cos(pan * PI/2); R = SQRT2 * > > sin(pan > > * PI/2), where pan value ranges from 0 (full-left) to 1 > > (full-right). _______________________________________________ Linux-audio-dev mailing list [email protected] http://lists.linuxaudio.org/listinfo/linux-audio-dev
