Fourier Transforms

Fourier transforms convert complex signals into a series of sinusoid waves. Since it's easy to create a sine wave with a microcontroller, you can perform a Fourier transform on a complex wave and reproduce it with sine waves.  A few sine waves could be used to generate the sounds of instruments, and many lossy files like JPEG are compressed using DCT, a form of Fourier transform.

48kHz 16-bit Stereo SPDIF

This has been out for a while, I just hadn't played with it before (check out the video to see what I'm talkin' about).  The audio quality is perfect - it's an amazing effort.  Just an SD card and an LED.  I modified it (very slightly) to work with SDHC and the Propeller Platform's pins, here's the code zip_small.gif
