The WRITE_WAV procedure writes the audio stream to the named .WAV file.
WRITE_WAV, Filename, Data, Rate
A scalar string containing the full pathname of the .WAV file to write.
The array to write into the new .WAV file. The array can be a one- or two-dimensional array. A two-dimensional array is written as a multi-channel audio stream where the leading dimension of the IDL array is the number of channels. If the input array is in BYTE format, the data is written as 8-bit samples, otherwise, the data is written as signed 16-bit samples.
The sampling rate for the data array in samples per second.
