Similar to the human cochlea where the different frequencies are split-up and analyzed, The Snail for iOS uses a spiral grid to visualize root notes and overtones of any incoming sound with utmost precision. The Snail is based on recently developed technology making instrument tuning easy and audio analysis music-oriented and fun to watch.
Tune any instrument with utmost precision
Version 2 offers an additional guitar tuning mode that is available in the tuning view. Just tap on a dedicated string name, play a note and adjust the guitar tuning accordingly. Another major improvement is the new split window mode. Whenever you do any adjustments to parameters you now see how the edits affect the visualization in the upper section. This works in both visualization modes. One mode is the snail grid, a complete musical overview of the audio spectrum. The other one, the tuner view, is especially designed to focus on the root note for tuning purposes. In both views there is a sine tuning oscillator available which is controlled simply by touching the desired note on the iPhone display. There are a lot of customizable parameters. No problem if you would like to tune transposing instruments or if you need a tuning reference other than 440 Hz.
Patented technology
The well-known IRCAM institute for acoustic and music research in Paris is responsible for the new technology of detection and visualization. It is a patented invention by Thomas Hélie, CNRS researcher at the Sciences and Technologies for Music and Sound (STMS) Laboratory (IRCAM/CNRS/Sorbonne Université). The Snail is also available for macOS and Windows, as stand-alone app or plug-in (VST3/AU/AAX), distributed by Plugivery.
