Audio Visualization

Visualize the waveform of an audio signal.

In[1]:=

rule30 = Import["ExampleData/rule30.wav"]

Out[1]=

In[2]:=

AudioPlot[rule30, ImageSize -> Medium]

Out[2]=

Plot the absolute values of the waveform.

In[3]:=

AudioPlot[rule30, Appearance -> "ContinuousAbs", ImageSize -> Medium, PlotRange -> All]

Out[3]=

Plot the waveform as discrete values, colored according to height.

In[4]:=

AudioPlot[rule30, Appearance -> "Discrete", ImageSize -> Medium, ColorFunction -> Function[{x, y}, ColorData["Rainbow", y]], PlotRange -> All]

Out[4]=

Plot the spectrogram and periodogram of an audio signal.

In[5]:=

Spectrogram[rule30, ImageSize -> Medium]
