SignalProcessing[SignalPlot] - plot a signal

Calling Sequence





string, rtable, or list; signals to be plotted



The SignalPlot command plots one or more signals. The input f can be the name of a file containing an audio signal, an rtable, or a list. See AudioTools:-Format for information about the kinds of files accepted.


If f is an m by n Matrix (or 2-dimensional Array), then it is assumed to contain n signals of length m. In this case, all signals are plotted and displayed in an array plot. Similarly, if f is an audio signal with multiple channels, then plots for all channels are produced.  If you do not wish to plot all signals, the channel and column options allow you to plot a subset.


If f is a list, then every element of the list must be a single-channel audio signal or a 1-dimensional Array.


The compactplot option allows multiple plots to be displayed more compactly. When this option is set to true, it is assumed the x-axis labels for all plots are identical and thus they are displayed for the bottommost plot only.


If the signal is particularly large and the reduceplot option is set to true, then the plot resolution is automatically reduced for efficient rendering. If reduceplot is a positive integer, then the plot is reduced by that factor. The default setting for this option is true.


The samplerate option is used to specify a sample rate. Note that audio signals generated by the AudioTools package have the sample rate saved in their attributes.


Additional plotting options as described on the plot/option help page may be included.
