The AudioTools package is a collection of utilities for reading and writing common audio file formats, and for performing basic audio processing operations within Maple.

Within Maple, audio data is represented as dense rectangular Arrays of 64-bit hardware floating-point numbers. Monophonic audio data is one-dimensional, whereas stereo (or more channel) audio data is two-dimensional (the second dimension representing the individual channels).

In addition to the commands in this package, many ordinary Array and Matrix operations are useful for audio processing. For example, combining one recording with another is done with the expression aud1*0.5 + aud2*0.5.

Each command and variable in the AudioTools package can be accessed by using either the long form or the short form of the name in the calling sequence.

The long form, AudioTools:-command, is always available. The short form can be used after loading the package.

The following is a list of available commands:
