IRCAM 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.

 

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.

 

TRAX Transformer - Real-time Voice and Sonic Modelling Processor

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

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

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.
