Some time ago I download a unit called WavePlayer.pas. The header of the file looks like this:
//This file introduces a class that is able to play waves and mpeg1 audio from
//resource, memory and disk via TStream class. It uses WAVE_MAPPER instead
//of PlaySound, so that you can play waves simultaneously.

Is this file related to the WaveAudio package? And if so, how much is in common?
