The Brittany-based consortium HDaudio3D (LabSTICC, Brest; Noise Makers, Rennes; and Feichter Audio, Lannion) has been working for five years on the development of a professional 3D audio recording solution: one offering sufficient spatial accuracy and signal-to-noise ratio, compatibility with headphones and speakers, and the ability to manipulate the audio scene in post-production. The solution is now operational and includes a 7th-order ambisonic sensor (with 480 MEMS on the surface of a 16 cm icosahedral tetrahedron), signal processing and a software suite. Pascal Rueff, a sound engineer specialising in binaural sound and François Salmon, research engineer at Noise Makers, members of the HDaudio3D consortium, will present the system and play excerpts from recordings made for various use cases.
