SpectralComplexity
standard mode | Spectral category
Inputs
- spectrum (vector_real) - the input spectrum
Outputs
- spectralComplexity (real) - the spectral complexity of the input spectrum
Parameters
- magnitudeThreshold (real ∈ [0, ∞), default = 0.005) :
- the minimum spectral-peak magnitude that contributes to spectral complexity
- sampleRate (real ∈ (0, ∞), default = 44100) :
- the audio sampling rate [Hz]
Description
This algorithm computes the spectral complexity of a spectrum. The spectral complexity is based on the number of peaks in the input spectrum.
It is recommended that the input "spectrum" be computed by the Spectrum algorithm. The input "spectrum" is passed to the SpectralPeaks algorithm and thus inherits its input requirements and exceptions.
