trajectories

spatial approach to rhythmic contours

This repository contains:

• electron app for path authoring
• max patch for applying the movement to a set of audio files

Electron app: visual indication of paths (trajectories) and dynamics of motion (rests, accelerations).

Trajectories exports a single multichannel wav file containing:

• doppler -- pitch-shift curve data according to doppler effect
• distance -- square law for distance-based attenuation
• azimuth -- angle from listener, normalized to be 0 to 1 for 360 degrees
• panning -- normalized L-R panning for exaggeration (0..1)
• velocity -- average is set to 0, accelerations & decelerations are mapped to [0..1] and [0..-1], respectively
