f0ac

F0 detection using autocorrelation, as described by Paul Boersma (1993: Accurate Short-Term Analysis of the Fundamental Frequency and the Harmonics-To-Noise Ratio of a Sampled Sound. Proceedings of the IFA. Vol 17. pp 97-110).

Usage:

f0ac(x, sr, hopsize, minf0, maxf0, nppw, nMaxCandidates, thSilence, thVoice, costOct, costOctJump, costVUV)

Parameters:

x

The signal vector.

sr

The sampling rate in Hertz.

hopsize

The hop size in seconds. The default is 0.

minf0

The minimum f0 in Hertz. The default is 75.

maxf0

The maximum f0 in Hertz. The default is 400.

nppw

The number of periods per window. The default is 3.

nMaxCandidates

The maximum number of candidates. The default is 15.

thSilence

The silence threshold. The default is 0.05.

thVoice

The voicing threshold. The default is 0.4.

costOct

The octave cost. The default is 0.01.

costOctJump

The octave jump cost. The default is 0.4.

costVUV

The voiced/unvoiced transition cost. The default is 0.2.

Result:

An f0 vector in Hertz.
