Acoustic and Cognitive Spaces 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 results of the research activities, implemented as signal processing libraries and applications, have been used and refined in the context of composition and real time sound transformation at IRCAM to provide efficient and extraordinary high quality transformations of music and vocal signals. The voice transformation algorithms have already been used, with success, in international and French cinema productions. (Farinelli, Vatel, Tirésia, Les amours d'Astrée and Céladon). The music and voice signal manipulation technology is available as three innovative transformation and cross-synthesis (TRAX) plug-ins. IRCAM Tools estimated for release SUMMER 2010

HEar - Binaural Encoding Tool
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.
Binaural technology
Binaural technology encompasses methods for recording, processing, synthesizing and reproducing sound that are specifically designed to preserve tridimensional localisation properties.
In order to mimic the impression of a sound originating from a given incidence, it is sufficient to filter a mono signal, which on its own lacks any kind of spatial information, with both left and right HRTF filters. This constitutes the foundation of binaural synthesis.
Please note that the resulting signal is only meant to be listened to with headphones, and isn’t designed for a conventional stereo loudspeaker setup.
Processing Specifications
Virtual head
This plugin relies on HRTF fi lter measurements made using a KEMAR (Knowles Electronics Manikin For Acoustic Research) dummy head and torso simulation. This type of manikin was conceived during the 1970’s for conducting acoustics experiments using a model with anthropometric dimensions equivalent to that of an average human listener. (Kemar head and torso simulation)

Verb Session - The Ultimate Session Reverberation Processor
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.
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.
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.
Each of the up to eight incoming audio channels is internally mapped to a range of Virtual Sources localized in a 3D space, and connected to a room (a reverb). Up to 3 rooms in parallel are provided, presenting the option to simulate complex spaces (coupled room acoustics).
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.
The SPAT licence includes the IRCAM Verb as well.
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 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 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 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.

Compressor, de-compressor, expander and de-expander which can all be independently contolled. In addition, here are some of the key features that make our plug-in the best available for dynamic processing in the digital domain :An analog like metering. RMS values are more useful than dB-fs when setting a dynamic processor.
The "Angel's Share" parameter takes into account the signal for intelligent relaxation of the compressor action.
The "Hysteresis" parameter allows compressing and de-compressing, independently of the sound level and can be mixed with the standard compression scheme.
The Auto Release features an unique algorithm that avoids typical pumping effect.
A delay line can be inserted in the signal path to produce a null attack time.
The A/B Compare and Morphing section enables ultra fast and precise operations.
Dry Mix function to achieve the full control of the dynamic processing amount.
Epure features for every section:
Individual bypass.
The filter type can be set to low cut, low shelving, peak, hi shelving, hi cut

Epure also features five unique functions to make equalization even more easy:
Copy A and Copy B duplicate the twenty settings of a slot to the other in one click
X2 and /2 affect the gain value for every equalizer section
Invert turns the positive gain values to negative ones and vice versa
Epure includes internal Input /output routings. A channel group management allowing to set many channels or individual channel setting is also available from the new setup window. From this window, up to 4 MS encoders and up to 4 MS decoders can be engaged if required. Combined with our exclusive A /B morphing system, these functions enable a global and efficient control of the equalization curve in a second.
Pure Limiter is supposed to be the very last stage of your audio processing chain. It uses the exclusive FLUX technologies to generate a release envelop producing no artefact on the processed sound.
A transparent limiting dramatically increasing the average audio level can now be achieved without damaging the perceived audio quality.
As usual with the FLUX plug-ins there is no compromise between simplicity of use and the exhaustiveness of the accessible parameters. An automatic mode allows quick operations in most cases. But a manual mode and an advanced mode are also there to allow you a total control on the processing.
To make the setting even easier, the Pure Limiter also features two display modes.
When the mode A is engaged, both original and limited waveforms are displayed.
The Mode B displays the limited waveform, the limiter action and the histogram of the release value which is especially useful when running in advanced mode.
