EnergyBand¶

Inputs¶

• spectrum (vector_real) - the input frequency spectrum

Outputs¶

• energyBand (real) - the energy in the frequency band

Parameters¶

• sampleRate (real ∈ (0, ∞), default = 44100) :

  the audio sampling rate [Hz]

• startCutoffFrequency (real ∈ [0, ∞), default = 0) :

  the start frequency from which to sum the energy [Hz]

• stopCutoffFrequency (real ∈ (0, ∞), default = 100) :

  the stop frequency to which to sum the energy [Hz]

Description¶

This algorithm computes energy in a given frequency band of a spectrum including both start and stop cutoff frequencies. Note that exceptions will be thrown when input spectrum is empty and if startCutoffFrequency is greater than stopCutoffFrequency.
