What is a noise pattern?

34. Pattern noise is a kind of spatial noise that is induced mainly by the non-uniformity of the pixels' responsiveness, and fixed deviations of performance between pixels in the absence of illumination. Here we focus on the random noise in individual pixels and the array.

What is noise frequency spectrum?

The audio frequency spectrum represents the range of frequencies that the human ear can interpret. Sound frequency is measured in Hertz (Hz) unit. This audible frequency range, in the average person at birth, is from 20Hz to 20000Hz, or 20 kHz. The hearing range of different animal species (From Wikipedia.com)

Which tool was used in the demo to Analyse audio files?
