The Snail is a very high-precision frequency-domain analyzer that delivers an easy to understand representation of sounds based on the scales and notes aligned in spectrally active zones.
It offers a new way of tuning and analyzing an instrument in an extremely accurate way, displaying intonation and visualizing music and sounds in a way that can help anyone improve their listening and intonation!
Think of a film camera turning at 24 frames per second filming a bicycle wheel turning at 24 revolutions a second, the spokes will appear to be standing still. That means, for a Fourier analysis of frequency at 439Hz compared to a tuning reference of 440Hz, the demodulated phase will turn at 1Hz (as a slightly desynchronised stroboscope makes a rotating object have a slow movement). Think of audio signals ’beating’ as there is a interference between two sounds at slightly different frequencies.
Compared to standard spectrum analyzers based on Fourier-type analysis, the frequency accuracy is enhanced by a process based on the demodulated phase. This system is based on a recent patented technology, conceived at the laboratory of Science and Technology of Music and Sound IRCAM-CNRS-UPMC.
This process has a dedicated algorithm which exploits the technology in several ways to:
1. Improve the frequency precision at an adjustable rate. Letting you fine-tune the accuracy of the Snail to get you an absolute tuning
2. Go beyond the global stroboscopic techniques used in some high-quality tuners by analyzing all the local spectral components and rendering this information in a convenient visual form. You see all the surrounding frequencies and overtones as well as the basic fundamentals.
3. Exploit the local information to deliver a new notion of tuning (available for slightly or highly inharmonic sounds) and to visualize the harmonicity quality (a “bad string” can be immediately identified or a resonance that is out of tune in your instrument, or resonances that cause some notes to be more present (ringing) than other - which might be desirable or not).
4. Extract those elements that prevent an accurate tuning from being done, like noise or speech from the surroundings which make tuning easier, without interfering with the accuracy. Filtering out unwanted frequencies are not part of the object of the tuning.
The “Snail” visualizer shows the active zones of the spectral content, represented as light spots on a spiral skeleton, built in such a way that:
• One turn is one octave. Low notes are close to the center, high notes are far from the center. The reference tuning frequency (default : 440Hz) is symbolised by the blue point attached to the skeleton. This provides an abacus adapted to the twelve- tone equal temperament.
• For each frequency, magnitude is converted into loudness and mapped to brightness : double the loudness of a component, it doubles the brightness of the spot. The spot thickness increases with respect to the loudness. Additional information is conveyed by colours, according to the selected modes.
• When the tuner layout mode is displayed a rotating hexagon the speed of its rotation allows the estimation of the very refined tuning, the slower the rotation the closer you are to being in tune. When it stops completely you are absolutely in tune.
This product is for Mac and Windows OS as a Standalone application, AAX, AU and VST plug-in.

Ircam Spat v3 – The complete Room Acoustics Simulation and Localisation Solution
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, Ircam Spat v3 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 v3 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 v3 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.

Ircam Verb v3 – Room Acoustics and Reverberation
Ircam Verb v3 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, Verb v3 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.

Ircam Verb v3 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 v3 – The Ultimate Session Reverberation Processor
Ircam Verb Session v3 is based on the same fine technology used in the acclaimed Ircam Verb v3 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 v3 presents the ultimate solution whether you are a seasoned session engineer or a demanding broadcast and post-production mixer.

Ircam HEar v3 – Binaural Encoding Tool
Ircam HEar v3 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 v3 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.

Ircam Trax Transformer v3 – Real-time Voice and Sonic Modelling Processor
Ircam Trax Transformer v3 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).

Ircam Trax Cross Synthesis v3 – Spectral Envelope Morphing Processor
Ircam Trax Cross Synthesis v3 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.

Ircam Trax Source Filter v3 – Enhanced Sound Filtering Processor
Ircam Trax Source Filter v3 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.
