spectrum analyzer plug-in for Mac OS X AAX, AU, VST designed to understand representation of sounds based on the scales and notes aligned in spectrally active zones.

process based on the demodulated phase

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.
