This project makes FEZ play audio with nothing but a PC speaker. This is not meant to play music but it is ideal if your product/project will need to voice out some commands or alerts. Maybe dial a number or playback a message … You can probably think of a million ways to use this.
The project plays two random number between 0 and 99 and randomly their addition, subtraction or multiplication. All audio files are saved on an SD card. They are PCM 8000KHz, 8 bit mono.
The files are read from the SD card and then parsed using a WAVE parser. The audio data is then sent to the analog output of FEZ.
The output is connected to an audio jack of a PC speaker. Basically, you just need ground and audio signal. See this: http://en.wikipedia.org/wiki/TRS_connector
The audio files included are NOT licensed fro commercial use. I found these somewhere while googleing.
