FrequencyNormalization

Correct for 1/f frequency falloff.

The frequency spectrum of the given data will be multiplied by its repective frequencies to correct for the typical 1/f falloff curve observed in spectral energy from natural sources. This filter will only process chunks that have a frequency axis (i.e., after transform into the spectral domain). More Info... Version 1.1.1
