The Normalize command adjusts the amplitude of samples in a recording so the maximum amplitude of any one sample is as specified.

The audArray parameter specifies the audio data to normalize, and must be a dense, rectangular, one or two dimensional Array, Vector, or Matrix with datatype=float[8].

The amplitude=value option specifies the maximum amplitude that any sample may have. If omitted, this defaults to 1.0.

The Normalize command is often useful after performing other audio processing operations that may have produced out-of-bound values, or very low amplitudes.
