After more than a year of intensive development, we are very proud to introduce Overtone Analyzer 2.0. This version was created in close cooperation with several voice teachers and sound experts who already use the software in their daily practice. This resulted in many small improvements in usability, but also in some large new features that simplify and accelerate the work with sound visualization.

Set Markers & manage Files
The biggest new feature for Overtone Analyzer 2.0 is the possibility to assign descriptions to whole recordings, and to individual passages within a recording. These markers are easily searchable. This allows to manage even large archives of recordings, so that you will always find the interesting parts in your sound archive.

Pitch Display
In addition to the spectrum and spectrogram, which are based on the Fourier analysis, Overtone Analyzer now has a separate pitch recognition module that assigns a fundamental pitch to each point in time of the recording with very high accuracy. This allows to measure and display the fundamental pitch much more easily, especially for deep tones. The pitch display shows very clearly if a tone has the intended pitch. Singers can see the pitch of the note onset as well as the quality of their vibrato. Instrumentalists can tune their instrument with extreme precision and use visual feedback to practice their embouchure and the accuracy of their pitch.
Vowel Chart
The vowel chart shows the relation betwen vowels and formants. The spectrogram and spectrum now have rulers that can be set to mark resonance frequencies, which will appear as lines on the vowel chart. This allows to assign those resonance frequencies to each vowel that form it. The vowel chart opens up many new ways of teaching and understanding the connections between resonance tones, formants, and overtones.
All Editions (Free, Live & Premium)
All editions get many improvements in the performance and usability of the program. Here are the most important ones:
- New piano keyboard
- Mouse wheel emulation: the keys 1 and 2 simulate the mouse wheel action for zooming and scrolling, which allows to easily zoom and scroll on a laptop that has no mouse wheel.
- Zoomable timeline: Ctrl+Mousewheel now zooms the timeline. This is especially useful for navigating long recordings with many markers.
- Improved tone generator: the sine wave generator has much better performance and can therefore play tones up to 20kHz (not just 10kHz as before). Note sliders can be moved during playback, and the frequency will be smoothly adjusted in real time.
- The piano can now also play sine waves.
- The timeline is now at the bottom by default, as many other programs have it there as well.
- During playback of loops, the beginning and end of the loop will be softly faded in and out to avoid loud pops.
- Extended mouse controls: Shift+Click sets the selection from the playback cursor to the clicked position. Ctrl+Click+Drag sets the selection and zooms to it immediately.
- When the spectrum is horizontal, the slider labels are now at the bottom so that the spectral peaks are not obscured by them.
- various bugs fixed
