Audio Demonstration

Summary: This module contains example audio files of mixed and recovered signals.

Audio Demonstration

The following signals are examples of audio files that we ran through our code. The two signals are linearly mixed, then run through Matlab code to recover the original signals.

Demonstration 1

This is an example of ICA being used to separate out individual voices from two people simultaneously talking. The first two are the linearly combined signals; the last two are the results of the ICA code.

AUDIO FILE: Mixed Signal 1A.wav

AUDIO FILE: Mixed Signal 1B.wav

AUDIO FILE: Recovered Signal 1A.wav

AUDIO FILE: Recovered Signal 1B.wav

Demonstration 2

This is an example of ICA being used to separate out individual songs that are playing at the same time. The first two are the linearly combined signals; the last two are the results of the ICA code.
