Frederick,

Jose asks a good question, M$oft ".WAV" format or raw PCM audio? HiFi or TinkerToy? There is actually a great deal of info on micro's emitting stored audio on the web. The ".WAV" format is not tricky or hard to find definition for. Also many utilities exist to convert ".WAV" files to different sample rates, bit depths, and alternate formats including "raw PCM".
