This function plots dynamically a sliding spectrogram along a time wave.

dynspectro

Functions for analysing, manipulating, displaying, editing and synthesizing time waves (particularly sound). This package processes time analysis (oscillograms and envelopes), spectral content, resonance quality factor, entropy, cross correlation and autocorrelation, zero-crossing, dominant frequency, analytic signal, frequency coherence, 2D and 3D spectrograms and many other analyses. See Sueur et al. (2008) <doi:10.1080/09524622.2008.9753600> and Sueur (2018) <doi:10.1007/978-3-319-77647-7>.

Dynamic sliding spectrogramn — dynspectro

<dl>

 <dt>wave</dt>
<dd>an R object.</dd>
 
 <dt>f</dt>
<dd>sampling frequency of <code>wave</code> (in Hz). Does not need to
 be specified if embedded in <code>wave</code>.</dd>

 <dt>channel</dt>
<dd>channel of the R object, by default left channel (1).</dd>
 
 <dt>slidframe</dt>
<dd>size of the sliding frame (in percent of the wave duration).</dd>

 <dt>wl</dt>
<dd>if <code>at</code> is not null, length of the window for the analysis
 (even number of points, by defaults = 512).</dd>

 <dt>wn</dt>
<dd>window name, see <code>ftwindow</code> (by default <code>"hanning"</code>).</dd>

 <dt>zp</dt>
<dd>zero-padding (even number of points), see <code>Details</code>.</dd>

 <dt>ovlp</dt>
<dd>overlap between two successive windows (in % ).</dd>

 <dt>fftw</dt>
<dd>if <code>TRUE</code> calls the function <code>FFT</code> of the
 library <code>fftw</code>. See Notes of the <code>spectro</code>.</dd>

 <dt>dB</dt>
<dd>a logical, if <code>TRUE</code> then uses dB values</dd>

 <dt>plot</dt>
<dd>logical, if <code>TRUE</code> plots in an ew graphics device the successive
 spectrograms sliding along the time wave (by default <code>TRUE</code>).</dd>

 <dt>title</dt>
<dd>logical, if <code>TRUE</code> adds a title with the time position of the current
 spectrogram along the time wave.</dd>

 <dt>osc</dt>
<dd>logical, if <code>TRUE</code> plots an oscillogram beneath
 the sliding spectrogram with a cursor showing the position of the 
 current spectrum (by default <code>FALSE</code>).</dd>

 <dt>tlab</dt>
<dd>title of the time axis.</dd>

 <dt>flab</dt>
<dd>title of the frequency axis.</dd>

 <dt>alab</dt>
<dd>title of the amplitude axis.</dd>

 <dt>from</dt>
<dd>start mark where to compute the sliding spectrogram (in s).</dd>

 <dt>to</dt>
<dd>end mark where to compute the sliding spectrogram (in s).</dd>

 <dt>collevels</dt>
<dd>a set of levels which are used to partition
 the amplitude range of the spectrogram.</dd>

 <dt>palette</dt>
<dd>a color palette function to be used to assign colors in
 the plot.</dd>

 <dt>envt</dt>
<dd>the type of envelope to be plooted:
 either "abs" for absolute amplitude envelope or "hil" for Hilbert amplitude envelope.
 See <code>env</code>.</dd>

 <dt>msmooth</dt>
<dd>when <code>env</code> is not <code>NULL</code>,
 a vector of length 2 to smooth the amplitude envelope with a 
 mean sliding window. The first component is the window length
 (in number of points). The second component is the overlap between
 successive windows (in %). See <code>env</code>.</dd>

 <dt>ksmooth</dt>
<dd>when <code>env</code> is not <code>NULL</code>,
 kernel smooth via <code><a href='https://rdrr.io/r/stats/kernel.html'>kernel</a></code>. See <code>env</code>.</dd>

 <dt>coltitle</dt>
<dd>if <code>title</code> is <code>TRUE</code>, colour of the title.</dd>

 <dt>colbg</dt>
<dd>background colour.</dd>

 <dt>colline</dt>
<dd>colour of axes line.</dd>

 <dt>colaxis</dt>
<dd>colour of the axes.</dd>

 <dt>collab</dt>
<dd>colour of axes title.</dd>
 
 <dt>cexlab</dt>
<dd>character size for axes title.</dd>

 <dt>fontlab</dt>
<dd>font for axes title.</dd>

 <dt>colwave</dt>
<dd>colour of the oscillogram or of the envelope (only when <code>osc</code> is <code>TRUE</code>).</dd>
