High frequency content measure High frequency content measure In signal processing, the high frequency content measure is a simple measure, taken across a signal spectrum (usually a STFT spectrum), that can be used to characterize the amount of high-frequency content in the signal. The magnitudes of the spectral bins are added together, but multiplying each magnitude by the bin "position" (proportional to the frequency). Thus if "X"("k") is a discrete spectrum with "N" unique points, its high frequency content measure is: In contrast to perceptual measures, this is not based on any evidence about its relevance to human hearing. Despite that, it can be
