Music: APL vs APS - Synthesizing Bach's Toccata and Fugue Using Array Programming

Explore the intersection of music and programming in this 39-minute conference talk by Ray Cannon at Dyalog '23. Delve into a decade-long journey of recreating J.S. Bach's "Toccata and Fugue in D minor, BMV565" using APL. Discover the intricacies of WAV file formats, chord composition, and harmonics. Learn how to synthesize organ pipe sounds, add reverberation for concert hall effects, and create animations to visualize musical notes. From turning a phone into a stylophone to understanding decibels and loudness reduction ratios, gain insights into various aspects of digital music production. Witness the culmination of these efforts with a full stereo rendition of Bach's masterpiece, complete with an animated visual representation of each note played.
