Calculate the energy (or power) spectrum of a frame of speech.

Documentation

Calculate the energy (or power) spectrum of a frame of speech. The FFT order is determined by the number of samples in the frame of speech, and is a power of 2. Note that the FFT vector returned corresponds to frequencies from 0 to half the sample rate. Energy is the magnitude of the FFT; power is the squared magnitude.
