Reply to comment by Mhmd1993 in Can someone explain what just happened? I turned the "Front Pink in" slider from 100 to 0 and the static noise in my headset disappeared. by Mhmd1993

Pink most likely means pink noise

And so you probably just turned off the pink noise generator.

Pink noise is sometimes used for calibration applications in sound studios. Like, for example, when you’re mixing sound for a feature film, at the end the Dolby engineer comes in to make the Dolby encoded audio and they have a special pink noise generator that they use to calibrate the sound of the studio to their theatrical standard.

Not sure what the use is here, but it’s probably related to testing whether your headphones / speakers have a flat frequency response.

Pink noise

>Pink noise or 1⁄f noise is a signal or process with a frequency spectrum such that the power spectral density (power per frequency interval) is inversely proportional to the frequency of the signal. In pink noise, each octave interval (halving or doubling in frequency) carries an equal amount of noise energy. Pink noise is one of the most common signals in biological systems. The name arises from the pink appearance of visible light with this power spectrum.
