Changed copyright notice so it is my actual name. Added a helper script to compile preferences and dependencies. Changed COMPILE instructions. 2006-09-04 18:46:18 +00:00			`// Created by Vincent Spader on 8/2/05.`

Core Audio: Overhauled audio output to use AudioQueue instead of AudioUnit, fixed downmixing to mono, and implemented upmixing mono or other formats to more channels if the device requests them 2021-12-26 06:32:43 +00:00
