An attempt to reproduce the effect of the drug diisopropyltryptamine on auditory perception.

The effect was created with software called SPEAR, which stands for Sinusoidal Partial Editing Analysis and Resynthesis. Essentially, the original sounds were broken down into a number of parallel sine waves, which are layered together to "resynthesize" the sound. Before resynthesis, however, I applied a global frequency shift to each partial, causing the harmonic relationships between the partials to be distorted (two partials with a 2:1 frequency ratio might now have a 2.2:1 ratio).

This gives many sounds a metallic or bell-like timbre, which is exemplified particularly well in Keith Jarrett's piano. It also breaks down the traditional harmonies of tonal music. DiPT had a virtually identical effect, which leads us to conclude that the human brain must similarly deconstruct sound into sinusoidal partials.

DiPT Effect On Auditory Perception

Playing a simple tune I wrote for class awhile ago.

A Glint In The Milky Way

made these chords while waiting for my tea to brew. =)

Probably the first time I've played a somewhat listenable piano improvisation...

My sister Sara helping me test my new Warbler MKVI microphone by singing against an instrumental track for My Cherie Amour by Stevie Wonder.

My Cherie Amour - Shure SM58

A synthetic simulation of an auditory hallucination experienced on twenty-five milligrams of the drug 4-hydroxy-N-methyl-N-ethyltryptamine, consisting of multiple sinusoidal tones, which exhibit phase interference as they overlap in pitch.
