.pitchDescriptives

internal

Performs parametric synthesis of sounds with harmonic and noise
components such as animal vocalizations or human voice. Also offers tools
for audio manipulation and acoustic analysis, including pitch tracking,
spectral analysis, audio segmentation, pitch and formant shifting, etc.
Includes four interactive web apps for synthesizing and annotating audio,
manually correcting pitch contours, and measuring formant frequencies.

.pitchDescriptives function

<dl><dt>time</dt>
<dd>a vector of time stamps in s</dd>
<dt>pitch</dt>
<dd>a vector of pitch values in Hz</dd>
<dt>smoothBW</dt>
<dd>a vector of bandwidths (Hz) for consecutive smoothing of
input using <code>pitchSmoothPraat</code>; NA = no smoothing</dd>
<dt>inflThres</dt>
<dd>minimum difference (in semitones) between consecutive
extrema to consider them inflections; to apply a different threshold at
each smoothing level, provide <code>inflThres</code> as a vector of the same
length as <code>smoothBW</code>; NA = no threshold</dd>
<dt>extraSummaryFun</dt>
<dd>additional summary function(s) that take a numeric
vector with some NAs and return a single number, eg c('myFun1', 'myFun2')</dd>
<dt>ref</dt>
<dd>reference value for transforming Hz to semitones, defaults to
C0 (16.35 Hz)</dd>
<dt>plot</dt>
<dd>if TRUE, plots the inflections for manual verification</dd></dl>
