Filtered White Noise

Extra Credit Assignment, ECE 5510, Fall 2006

Assignment: 

Generate a 3 minute track of filtered white noise.  The sound must be generated using white noise (an i.i.d. random sequence) input to an LTI filter.  The filter is selected individually such that the output is judged to be (subjectively) 'soothing'.  The filter and the output (power spectral density and autocorrelation function) must be analyzed in the time and frequency domain, and verified by Matlab experiment, as described in the assignment handout.

Which sound is the best track?

After listening to the sound files, vote for the most soothing white noise sound track.
