My mix has five parts which should be clearly distinguishable. The breakdown of section length versus what I am trying to demonstrate is shown below: 1: 12 seconds - Changing Octaves and Interval 2: 12 seconds - Changing Octaves, Loudness, Timbre, Interval, and Pitch 3: 6 seconds - Changing Location 4: 12 seconds - Changing Octaves, Loudness, Timbre, Interval, and Pitch 5: 12 seconds - Changing Octaves, Loudness, Timbre, Interval, and Pitch I believe each section exemplifies the auditory streaming illusion in some sort, the 6 seconds where location is changing may be the most interesting to hear on the 4 channel system.
