Serving audio files may be useful to applications that need to present sampled voice or music sounds. However, serving static samples may not be too limited for applications intended to be dynamic.

This class provides a means to dynamically manipulate and output one or more audio files in the WAV format. It can apply several types of sound effects and combine multiple audio samples to form a single result output.

These sound processing capabilities open many different possibilities for applications that can benefit from dynamically generated audio samples.
