Abstract
Dream Structures is a live coding performance that uses computational audio analysis and machine learning to navigate and resample a half-terabyte archive of 90s/00s trance music, creating a live musical collage that organises fragments of audio from thousands of tracks by traversing a multidimensional feature space.

Dream Structures DANIEL JONES, Independent, United Kingdom Additional Key Words and Phrases: live coding, machine learning, music information retrieval, trance, electronic ACM Reference Format: 1 PROGRAM NOTES Dream Structures is a live coding performance that uses computational audio analysis and machine learning to navigate and resample a half-terabyte archive of 90s/00s trance music, creating a live musical collage that organises fragments of audio from thousands of tracks by traversing a multidimensional feature space. The system automatically mines this archive for sounds of certain categories commonly found within early trance and rave – animal sounds, speech, sirens, atmospheric noise – and uses them to generate both ambient textural and rhythmic sequences, using generative patterns that are developed on-the-fly in code. This is augmented by arpeggiated layers and pads using novel software emulations of iconic digital synthesizers including the Roland JP-8000 Super Saw, Akai MPC timestretch, DX7 FM synth. Dream Structures is performed with SignalFlow, a free and open-source Python library for sound synthesis that the author has been developing over the past decade, using Jupyter notebooks as a real-time IDE. All of the synthesis algorithms described are provided for free with the distribution. 2 PERFORMANCE NOTES •Duration: 10-15 minutes. • Requirements: HD projector and stereo audio input, ideally performed after dark in a club environment. 3 MEDIA LINKS • Short video here from a recent performance at 10 Years of Algorave (Corsica Studios, London, UK): https://www.dropbox.com/s/actyzfee7q3w3k4/IMG 4406.MOV?dl=0 Licensed under a Creative Commons Attribution 4.0 International License (CC BY 4.0).
