Mike,

Sound is nonlinear with respect to both frequency and loudness. The big difference between audio and imaging is that the devices we use to capture audio are already nonlinear�microphones behave very much like human ears. Photon counters do not behave at all like human eyes.

Gamma correction has absolutely nothing to do with CRTs, and everything to do with the human visual response. We do it with imaging because our imaging detectors don't behave like our senses. We don't do it with audio because our audio detectors DO behave like our human senses. Equalizers compensate for room conditions and speaker biases�they don't remap the sound to accomodate the nonlinearities of our ears because the mechanical components in the reproduction chain (the microphones and speakers) have already done so.

If your double the power going to a loudspeaker, is the resulting sound twice as loud?
