anyhow im sure most people here know what panning is...although i have never heard of a panning 'law'...so thank you for that information... |
Quit being a smartass. If you don't know what you're talking about, then just don't say anything!
He is actually referring to "panning law", and not panning. And panning law is exactly as he explains : the behaviour of the panpot in relation to volume. If there would be no panning law, the volume of the sound coming from the speakers would remain the same. Take a sound panned full left or right, and measure the volume. Now pan the sound in the middle. The same sound will come from both speakers. With no pan law, each speaker would put out the same volume as would you have panned hard left or right. But the listener sits between the two speakers, therefor hears the sum of the two. 2 times the same sound means +3 dB in power. So, merely panning from middle to side will result in an audible drop in volume. Hence the panning law where a gradual attenuation is induced towards the middle, to keep volume of the source constant.
In some programs you can decide how much attenuation takes place (SX for example). Most programs use 3 dB though (Reason also if I'm not mistaken, as it's pan is constant power based. As far as I know it's a fixed setting).
Oh, and BTW, a true stereo channel doesn't have a pan control, it's called balance there...
