PitchYinProbabilities
standard 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.
