Pink Noise

Pink noise is a kind of random noise which has equal energy in different octave ranges. It derives from white noise which is a random signal with wide frequency range and equal power for each frequency. Since the number of frequencies in octave doubles for each octave increase, the energy of white noise doubles in each higher octave as well, which is 3 dB/oct. boost. In other words, white noise gives the impression of high-frequencies dominance. In pink noise, the energy falls proportionally to frequency. I.e., it is similar to white noise, but with 3 dB/octave attenuation, starting from 1 Hz. This gives a much more even result from a human ear perspective, and the spectrum of pink noise is the closest one to an average music signal.

Peak Normalization

Peak normalization of an audio file or its part is a linear change of its whole gain that makes the amplitude level of its (PCM) sample with the maximum amplitude equal to a certain value (in dB).
