LiveSpat

Live Spat is a web app to handle the spatialization of sound sources. It helps defining (or drawing) the trajectory of a sound inside a fixed speakers configuration (stereo, quad, etc.)

dev path

4 TODO steps

• V0 Generate trajectory files from drawings. These files can be used by music composition software (eg Pure DAta, Supercollider)
• V1 Generarate "Score" files. Assing sound files to trayectories creating combinable track to programming the evolution of spatialization in a composition
• V2 Multiuser live version using Javascript Audio API
• V3 Multiuser live version using OSC messages in real-time to be consumed by musical software/hardware

Trajectory file format

is a text file which contains the information of the trajectory. data is separated with spaces.

Headers are these ''' BEAT, TRAJ_ID, SOUND_SOURCE, X, Y, RADIO, THETA, SPEED '''

• TRAJ_ID to be used in V1
• SOUND_SOURCE to be used in V1
• BEAT time to process the point
• X x cartesian coordinate
• Y y cartesian coordinate
• RADIO radio of polar coordinates
• THETA angle in degrees of the coordinate
• SPEED speed factor. Used to change the read tempo and also to produce a pitch shift -doppler-

To start your Phoenix server:

• Install dependencies with mix deps.get
• Create and migrate your database with mix ecto.setup
• Install Node.js dependencies with npm install inside the assets directory
• Start Phoenix endpoint with mix phx.server

Now you can visit localhost:4000 from your browser.
