Flux IRCAM Tools Software 1.1
Flux, in collaboration with IRCAM, proudly announces IRCAM Tools Software. The IRCAM Tools products express the result of over twenty years of fundamental research within the realms of music related digital signal processing. IRCAM Tools is a series of products evolved from two major fields of technology, 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. In other words, the localization of sound in space, and the specific acoustical characteristics of a room or of an environment.
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.
Sound Analysis and Synthesis
The sound analysis/synthesis team at IRCAM conducts research and development in the area of sound analysis, transformation and synthesis. The objective of the research on sound transformation is to provide signal transformation algorithms that allow modifying of sound characteristics such as pitch, timbre (spectral envelope) and duration (stretching/compression), using perceptual and intuitive controls.
The advanced sound transformation algorithms also provide independent controls for other perceptual sound characteristics; level of sinusoidal, noise and transient signal components. The voice transformation is controlled by high-level concepts such as age and gender, as well as by fine-tuning of the formant structure and the prosody. The results of the research activities, implemented as signal processing libraries and applications, provide efficient and extraordinary high quality transformations of music and vocal signals.
The software implementation has been used and refined in the context of composition and real time sound transformation at IRCAM, and the voice transformation algorithms have already been used, with success, in international and French cinema productions. (Farinelli, Vatel, Tirésia, Les amours d'Astrée et Céladon). The music and voice signal manipulation technology will be available as three innovative transformation and cross-synthesis (TRAX) plug-ins.
The IRCAM Tools bundle contains the following plug-ins:
•TRAX Cross Synthesis
•TRAX Source Filter
SPAT - Room Acoustics Simulation and Localisation
With more than a decade of research performed by the Acoustic and Cognitive Spaces Team at IRCAM, being at the forefront of scientific and technological innovations, the SPAT is the most advanced and sophisticated tool for room acoustics simulation and localisation ever designed, managing both spatialisation (source localisation) and room acoustic simulation in a truly consistent and visually logical way. SPAT introduce state of the art techniques for room acoustics simulation utilizing advanced perceptive models, concealing the complexity behind the actual algorithms, allowing for intuitive and accommodating user interaction capabilities. Designed for surround and multi-channel use, SPAT presents the option to setup the output arrangements providing a variety of stereo and surround configurations, including subwoofer configuration. With eight input and output channels available in SPAT, configurations up to 7.1 and 8.0 are feasible.
VERB - Room Acoustics and Reverberation
VERB is an algorithmic room acoustics and reverberation processor. It has a modular construction, employing a recursive filtering reverb engine, reproducing and synthesizing the specific acoustical characteristics of any spatial sound environment. Following a decade of intense research by the Acoustic and Cognitive Spaces Team at IRCAM, the IRCAM VERB introduce state of the art techniques for room acoustics simulation utilising advanced perceptive models, concealing the complexity behind the actual reverb algorithms and allowing for a flexible and intuitive experience for the user. The IRCAM VERB provides eight input and output channels, presenting the option for reverberation processing in multi-channel and surround formats. A built in Input/Output (I/O) routing matrix provides instant flexibility when setting up the I/O in relation to the physical audio monitoring in the control room.
TRAX Transformer - Real-time Voice and Sonic Modeling Processor
TRAX Transformer is based on an augmented phase vocoder technology, and a cutting edge transformation algorithm, allowing for manipulating characteristic properties of a voice such as gender, age and breath, and on any other sound; expression, formant and pitch. These voice transformation algorithms have already been used, with great success, in international and French cinema productions. (Farinelli, Vatel, Tirésia, Les amours d'Astrée and Céladon).
TRAX Cross Synthesis - Spectral Envelope Morphing Processor
TRAX Cross Synthesis utilizes a phase vocoder (the amplitude and the frequency/phase spectra), to morph the spectral characteristics of two sounds. The amplitude and frequency/phase spectra can be blended continuously and since the features that are used here are strongly nonlinear, the sound morphing is nonlinear as well, offering a way to create a wide range of new exciting and unusual sound effects.
TRAX Source/Filter - Enhanced Sound Filtering Processor
TRAX Source Filter is based on a signal model decomposing the signal into a time envelope describing the energy/loudness contour of the sound, and a spectral envelope describing the spectral colour of the sound timbre. The energy contour and the spectral colour of the source sound, can be continuously blended with the spectral colour and energy contour of an arbitrary filtrating sound, allowing transformation that extend well beyond the more common source filter morphing effect.
IRCAM VERB Session
VERB Session is based on the same fine technology used in the acclaimed IRCAM VERB algorithmic room acoustics and reverberation processor, with a modular construction employing a recursive filtering reverb engine, reproducing and synthesizing the specific acoustical characteristics of any spatial sound environment, developed utilizing the results of over a decade of intense research by the Acoustic and Cognitive Spaces Team at the IRCAM R&D centre in Paris.
Tailored for simplicity, with a fast paced workflow well-suited for situations where the perfect result has to be achieved within seconds, VERB Session presents the ultimate solution whether you are a seasoned session engineer or a demanding broadcast and post-production mixer.
HEar - Binaural Encoding Tool
HEar provides faithful reproduction of a stereo or surround mix with a pair of conventional stereo headphones. It relies on proven technology to model the various phenomena that occur when playing back audio material through a loudspeaker system.
This allows monitoring a full surround mix in situations when a surround-capable environment is not available or practical. Another typical use of HEar is doing precise checking of a mix, which is convenient with headphones as these provide a ‘surgical’ and very detailed, microscope-like rendering of the audio. HEar can also prove very useful in a project studio context, and whenever noise isolation is a concern, as it helps achieving a more realistic sound environment.
