[调性分析软件]IRCAM Lab The Snail v1.2.12 Incl Keygen -R2R[(WIN,OSX)](74Mb)

Snail 长得有点非主流,六角形的界面显示各个音调。这是一个基于频率的高解析度分析器,它会把高频到低频的音调都在这个六角形的界面上显示出来,并且会根据音频实时跟进。

Ircam Lab 表示,现在的调性分析软件一般都是基于傅里叶级数分析,而 Snail 波形解析技术是基于 IRCAM-CNRS-UPMC 的专利技术,这项技术已经得到了音乐科技&科学协会认证。因此 Snail 能够带来更为精准的分析结果,并且甚至能够显示出其他音调的和声,比如分析其他和弦时,Snail 还可以侦测并分析回响中的其他音调。当然如果觉得这太过于精确,用户还可以调整频率范围,已得到最适合的结果。

Snail 背后的技术肯定是十分复杂的,一下子要理解有点困难。但可以确定的是,这是一款简单实用的调性分析软件,高精度的准确度和六角形显示界面相信会帮助你提高听力。

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 innotation!

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.
