2.0.0 28 October 2011
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.
Overtone Analyzer Premium
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.
Overtone Analyzer Live & Premium
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.

1.5.2 29. July 2010
- The software is digitally signed now. This might reduce the occasional false alert from some virus scanners.
- some minor fixes
1.5.1 19. July 2010
This is a maintenance release with some small bug fixes. You only need this version if you were affected by the problems mentioned below. There will be a bigger update with many new features in a while.
- Bugfix: crash at startup for screen color depths other than 32 bit
- Bugfix: under some conditions saved sound files were not readable by some other audio applications
- Bugfix: the font of the note sliders could not be changed
- various other small fixes
1.5.0 May 10, 2010
- The Live Edition now also supports unlimited recording and editing of audio files!
- Many new entries in the 'Edit' menu:
- Normalize volume: increase volume of sections that are too quiet.
- Set selection: opens dialog to exactly specify the selected time range.
- Replace with silence
- Insert silence
- Overtone Analyzer can now open almost all know audio and video file formats. When opening videos, the first audio track will be automatically loaded.
- The Premium Edition has a new feature to open multiple windows on a single file. This makes it very easy to compare different parts of a recording that are not next to each other. To open a new window, select a time range and then click 'Window / New window of current selection'.
- When the time slider is moved during playback, the playback position will immediately jump to the beginning of the new range. This makes it much easier to search a long recording.
- The Overtone Sliders can now be resized and positioned independently of each other.
- Peak files are now cached. This increases the speed of opening previously files dramatically.
- Resizing the application window is much smoother now.
- The command 'lock selection' has its own icon on the toolbar now (the lock icon).
- Various bugfixes.
- Pressing the space bar while recording will stop the current recording without starting playback.
- Ctrl-W closes the current file
1.3.0 Dezember 3 2009
- Drawing the spectrogram is up to 300% faster than version 1.2.0. This allows smooth scrolling on most machines now.
- The spectrum is now drawn with smooth (anti-aliased) contours, which improves the image quality significantly.
- When the note sliders are transparent, only the area hidden by the sliders becomes darker. Previously, the entire screen was obscured.
- various bugfixes
1.1.0 18. May 2009
- The frequency scale can now be panned and zoomed, which makes working with the program much more fluent.
- Most views and scales now offer mouse wheel support for zooming or scrolling.
- The Overtone Sliders can now snap to the nearest peak in the spectrum. This allows highly accurate frequency measurements. The snap mode can be adjusted under Options / Note Sliders or on the toolbar.
- Different profiles for planetary tones, singing and speaking voice ranges can now be selected directly in the main window when the mouse moves over the window with those ranges (the window with the clef to the left of the piano).
- The Overtone Sliders are now slowly becoming real Note Sliders. They are no longer limited to be fixed on the screen and can also be assigned to a time segment of the recording (in other words, a note). This allows to transcribe entire pieces, and to export the note sequence as MIDI.
- various bugfixes
1.0.7 5. March 2009
- fix some problems with special characters in license key data
- fix problems with saving files whose filename or path contains special characters
- fix occasional stopping of recording or playback that occurs on some systems
- expose Playback Frame Rate setting in the advanced options
