PitchYinProbabilities¶

streaming mode | Pitch category

Inputs¶

signal (vector_real) - the input signal frame

Outputs¶

pitch (vector_real) - the output pitch candidate frequencies in cents

probabilities (vector_real) - the output pitch candidate probabilities

RMS (real) - the output RMS value

Parameters¶

frameSize (integer ∈ [2, ∞), default = 2048) :
number of samples in the input frame

lowAmp (real ∈ (0, 1], default = 0.1) :
the low RMS amplitude threshold

preciseTime (bool ∈ {true, false}, default = false) :
use non-standard precise YIN timing (slow).

sampleRate (real ∈ (0, ∞), default = 44100) :
sampling rate of the input audio [Hz]

Description¶

This algorithm estimates the fundamental frequencies, their probabilities given the frame of a monophonic music signal. It is a part of the implementation of the probabilistic Yin algorithm [1].

An exception is thrown if an empty signal is provided.
