SoundXY4 is an ambisonics system for music performance with a tangible interface. The project "SoundXY4: The Art of Noise" is a celebration of 100 years of Russolo's "The Art of Noise". The system includes 6 white cubes, which each represents one of the 6 sound categories in the "Art of Noise". There are also black cubes, which represent filters that can modify the sound of the nearest white cube. SuperCollider was used for the visual feedback as well as for the audio engine and program logic. The object tracking was processed using reacTIVision, based on fiducial markers. The SETO Quark was used for TUIO protocol management in SuperCollider. The sound samples selected are from Freesound.org. The angle of the white cube on the table surface defines the position of the sound source in the room using ambisonics. The audio of the video is a stereo representation of the ambisonics system, yet the system works best using at least 4 speakers. So, there is loss of data in the stereo image but it gives an idea of the effect. The SoundXY4 code is publicly available at: http://github.com/axambo/soundxy4
