Product comparison
Our sound visualization software comes in several different editions with different feature sets. The entry-level editions are priced to match the cost of one or two voice lessons and are intended for vocal and instrumental practice.
The professional edition has additional features for high-accuracy measurements and advanced comparisons of sounds.
Overtone Analyzer and VoceVista Video used to be separate products created by different teams, but they have been merged in 2017. They are now different editions of the same software and share the same user interface, but have different feature sets.
Overtone Analyzer lets you record sound while seeing and analyzing it in real time. The visualization shows the fundamental pitch and the overtone spectrum of the sound. This shows you which frequencies are in your sound, and how loud they are. Unlike many other spectrum analyzers that are primarily for experts with a background in the physics of sound, Overtone Analyzer helps to visualize the musical interpretation of the sound, and to understand the role of harmonic overtones, especially in the voice.
Overtone Analyzer also offers the most important functions for quick post-production, and editing of recordings, without a long learning curve.
VoceVista Video adds side-by-side comparison of recordings. This allows to compare multiple takes of the same exercise, or to compare the performance of a teacher and a student.
It also has real-time Frequency Filters, which allow to interactively filter parts of the spectrum in order to better understand many aspects of the voice (such as timbre, and singer‘s formant).
The Vowel Chart helps to understand how the harmonics in the voice create vowels.
In addition, VoceVista Video will soon offer synchronous recording and playback of videos of students or patients.
VoceVista Video Pro adds spectra and spectrograms at ultra-high frequency resolutions for highly accurate measurement applications.
It also adds the Long Term Average Spectrum to display and compare the spectral envelope of longer passages.
Markers allow to label sections of a recording, so that finding individual passages is easy, even in longer recordings.
VoceVista Video Pro also offers support for the Electroglottograph (EGG), and for advanced analysis and export features.
