Trajectoires: a Mobile Application for the Control of Sound Spatialization

Jérémie Garcia, Xavier Favory, Jean Bresson
(2015)

Trajectoires is a mobile application that allows drawing sound sources trajectories. The trajectories remotely control any spatial audio renderer using the OpenSoundControl protocol.

We are investigating the new possibilities offered by mobile devices such as smartphones and tablets to support sound spatialization control by composers. This project aims at combining gestural input with touch input to draw trajectories and the sensors integrated such as accelerometers and gyroscope to compute orientation with algorithmic processes in Max or OpenMusic.

Max / OpenMusic patches

Max patches (after 1.0)

To use these examples, you need to have the Ircam Spat installed and authorized. You also need Max6 or Max7.
The traj-max-4sources-demo.zip archive contains a single patch able to use the data from Trajectoires directly to the spat-oper object.

Note that you can also use the trajectories created with the application within Antescofo. To do so, you need to export a trajectory (bottom-right button of the interface) and then find the traj folder located near the Traj.app application. In the traj folder there is a text file containing the data associated with the trajectory that can be directly loaded by antescofo. This trajectoires-to-antescofo example loads a trajectory and plays it for the duration of a sound in antescofo.

Max patches for older versions (before 1.0)

These patches work with the previous version of Traj that can be downloaded here :

To use these examples, you need to have the Ircam Spat installed and authorized. You also need Max6 or Max7.
The Traj-Max.zip archive contains the following elements:

OpenMusic patches

To use these examples, you need to activate the reactive mode in the OpenMusic preferences and have the OMChroma and OMPrisma librairies.

The OM6-trajectoires-patches.zip archive contains the following patches:

These videos illustrate the use of Trajectoires and possible applications.
Please use headphones as the videos use binaural sound.
