PitchFilterMakam

Inputs

• energy (vector_real) - vector of energy values for the input frames
• pitch (vector_real) - vector of pitch values for the input frames [Hz]

Outputs

• pitchFiltered (real) - vector of corrected pitch values [Hz]

Parameters

• minChunkSize (integer ∈ [0, ∞), default = 10) :

  minumum number of frames in non-zero pitch chunks

• octaveFilter (bool ∈ {true, false}, default = false) :

  enable global octave filter

Description

This algorithm corrects the fundamental frequency estimations for a sequence of frames. The original estimations can be computed with the PitchYinFFT algorithm.

The algorithm is based on the code of Makam Toolbox 1.0. ftp://ftp.iyte.edu.tr/share/ktm-nota/TuningMeasurement.html
