Flux:: Sound and Picture Development, in collaboration with IRCAM (Institut de Recherche et Coordination Acoustique/Musique), have announced the new IRCAM Tools range of signal processing products.

The products fall into two groups: Acoustic & Cognitive Spaces, and Sound Analysis & Synthesis.

Acoustic and Cognitive Spaces

The research and development activity carried out by the Acoustic and Cognitive Spaces Team (formerly Room Acoustics Team) concentrates on the analysis, reproduction and synthesis of spatially considered sound environments.

The reproduction and synthesis of a sound environment depends on both techniques of signal processing, controlling the manner sound is diffusing from the speakers, and on physical/perceptive models of the spatial properties of the room’s sound sources.

Acoustic and Cognitive Spaces products include:

SPAT — Multi-format Room Acoustic Simulation & Localization Processor
VERB — Room Acoustic & Reverberation Processor

Sound Analysis and Synthesis

The analysis of sounds includes methods enabling the permanent extraction or automatic structuring of diverse sorts of information given off by a signal, such as the fundamental frequency or the spectral evolution determining the pitch and timbre of a perceived sound.

Information outside what is strictly musical is also taken into consideration, notably concerning industrial acoustics, sound design and multimedia as well as the automatic indexing of recorded sounds.

The methods used are based on signal processing, statistical analysis, information theory, machine learning and recognition techniques, but also on knowledge of auditory perception and acoustic system sound production.

Sound Analysis and Synthesis products include:
