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. Real-time spectral filters allow to interactively understand many aspects of the voice (such as timbre, and singer‘s formant).

Overtone Analyzer also offers the most important functions for quick post-production, editing, and documenting of recordings, without a long learning curve.

Finding individual passages for targeted listening is easy, even in longer recordings. Voice patients or students can hear and see their progress.

In addition, VoceVista Video offers synchronous recording of videos of students or patients, and the EGG (electro- glottograph).

VoceVista Video is an updated version of VoceVista, offering the same features as Overtone Analyzer, but with the addition of Video and EGG recording.

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 editions have additional features for high-accuracy measurements and advanced comparisons of sounds.
