Conference Schedule

3Dj is a SuperCollider library for real-time interactive 3D sound spatialization. It arises from the need of a free, multiplatform, Linux-compatible framework for sound spatialization. 3Dj is implemented in a modular way. On the one hand, the Scene Simulator provides convenience abstractions for handling sound objects in a virtual environment (physical modeling, predefined motions, visualization). These informations are sent through OSC to the Spatial Render, which synthesizes the resulting audio. Rendering can be done in Higher Order Ambisonics (up to 3rd order), VBAP or HRTF. Communication is based on the SpatDIF protocol, facilitating the use of alternative simulators/renders. SpatDIF recording and playback capabilities are also provided. 3Dj is implemented in SuperCollider, and makes use of several free software audio projects (Ambisonics Toolkit, AmbDec, Jack).
The talk will be complemented with a demonstration of the software in the installation space.

Music Information Retrieval is a field with a strong potential for artistic and performative usages. However, existing MIR tools are often interfaced by code, thus limiting access to people without programming knowledge. We present RTML, a graphical framework for Real-Time Machine Listening written in SuperCollider. RTML provides compact and simplified access to low- and mid level descriptors, and convenient utilities to map descriptor outputs with external applications through OSC.
The talk also serves as a background for the author's "Listening Lights" performance at the Linux Sound Night.

This is a demonstration of the 3Dj SuperCollider framework for real-time sound spatialization. In the demonstration, we will explore several metaphors for sound diffusion, as algorithmic spatialization, direct sound position control through orientation sensors, or spatialization based on Music Information Retrieval. Sonic material will be both existing fixed media and live produced electroacoustic sound.

Vagabundo Barbudo is an electro-experimental dance music project. Music is produced with free software tools, and distributed with copyleft licenses. Furthermore, "source" tracks are also distributed, in order to encourage modifications. Listening Lights is a project for automatic lighting of music. The core of the project is RTML, a graphical SuperCollider framework for Real-Time Music Information Retrieval.
In the performance, the music from Vagabundo Barbudo will be played, along with automatic reactive lighting provided by RTML.
