These synthetic microphone outputs formed the input to the Bell-Sejnowski Independent Components Analysis algorithm. The sources are somewhat separated in the output of the Bell-Sejnowski ICA algorithm, but not fully.
The same synthetic microphone outputs were then used as input to our new cICA algorithm (see my publications page for technical details). The sources are almost fully separated in the output of cICA.
Tracks 1-8 constitute the demo proper. Tracks 9 and 10 are bonus tracks, not on the original album!!!

Although the demo used only ten audio sources, I have sixteen available for experiments. They are available in two forms, via the following pages: as .wav files, as compressed ascii text, and, for truly blind experiments, as ten pre-mixed .wav files, the same ones used in the demo above. There are also some notes describing exactly where these audio files came from.
In our experiments with cICA, we converted to mono and downsampled by a factor of five. For a truly fair comparison with another algorithm, you should do the same.
