VoceVista Video 5.7.0

Screenshot of VoceVista Video Pro

This release brings together several new features that we wanted to do for a long time, many of which depend on each other. This includes various changes to the underlying architecture of the software, which are not directly visible to the user, but which were necessary to make the new features possible.
One of those architectural changes is the whole file pitch cache. In previous versions of VoceVista, the pitch track was derived from the visible spectrogram. This means its accuracy was dependent on the current time zoom level, and this would give different results for different zoom levels. The new pitch track is maintained independently of the visible spectrogram, so it always has the same accuracy regardless of the zoom level. This allows the mean pitch and also the vibrato tracks to be calculated with more accuracy and robustness. It also allows to export the pitch track of the entire recording to a spreadsheet file, and it will allow to easily compare pitch tracks of different recordings in future versions of VoceVista.

Another exciting new feature are the Smoothed Curves. This allows averaging of the spectrum over the frequency axis, which reveals the underlying spectral envelope. This is included in VoceVista Video 5.7.0 as an experimental new feature, and it will probably evolve into an official formant tracker in future versions.

Some new features for VoceVista Video Pro are a greatly revised Analysis View that provides numerical output of many metrics, along with the new Export Data feature that allows exporting many items to a spreadsheet file that can be opened in Excel, LibreOffice, and other programs that can read .xlsx files. This goes together with the new ability to analyze a set of checked Markers simultaneously for comparison.

The UI for the Long-Term Average Spectrum has been changed, so that the LTAS is now separate from the current selection (although this can be set to the previous behaviour as explained below). This allows to work with time selections without the LTAS getting in the way when it is not needed. Similarly, the cursor crosshair has been separated from setting the current spectrum, so that these two features can be used independently.

And as usual, this new version comes with a long list of bug fixes and improvements for usability, stability, and performance.

Also, we are working hard to update the user manual for all these new changes, and to create new video tutorials. As this will take some time, we decided to release this version 5.7.0 without the new manual, and strive to release the new revised manual in the coming weeks.

New Features

Whole file pitch cache

  • The pitch line is now more stable when zooming the displayed time range in and out, because it is calculated at a fixed time resolution, instead of being calculated at the current time resolution of the spectrogram.
  • This allows the mean pitch and vibrato analysis to be calculated independently of the visible range of the spectrogram.
  • The pitch time resolution (by default 100 points per second) can be specified on the Analyzer View / Vibrato settings page.
  • When the view is zoomed-out very far, the pitch track will be drawn as points instead of continuous lines.

Cursor and Mouse Hover

  • The cursor crosshair visibility is now separate from spectrum updating. So it is possible to enable the cursor crosshair, but uncheck the Enable hover spectrum option.
  • The options for this can be set on the Pointer & Selection settings.
  • The grey cursor lines have been reviewed and fixed to be more consistent across all views.
  • The context menu entries for the cursor text display on the short-term view have been consolidated into a single entry.
  • Only visible curves are now traced on the short-term view.
  • The text of the toggle snapping button has been changed into Toggle Cursor and Slider Snapping, as it applies to both.

Customizable Toolbars

  • The toolbars can now be fully customized through the menu Tools / Customize toolbars.
  • The toolbars can be detached from the main window, and used as floating toolbars, for example to have them on a separate screen.


  • The options/preferences window has been renamed into Settings.
  • New tool icon for the settings window.
  • Analyzer Settings: express FFT and pitch time resolutions as fractions of 1 second instead of steps/s.

Smoothed Curves

  • Allow display of smoothed versions of the current spectrum, the Long-Term Average Spectrum, and the average spectra of Markers that are checked for comparison. This is different from the Long-Term Average spectrum, which applies an averaging over time. The Smoothed Curves, in contrast, apply averaging over the Frequency axis, which can be used to reveal the underlying spectral envelope. These two calculations can be combined by applying the smoothing to the average spectra.
  • The Smoothed Curves can be enabled in the context menu of the Short-term View (by right-clicking on the Spectrum), and on the Analyzer View / Acoustic settings page.
  • The radius of the averaging can be specified on the Analyzer View / Acoustic settings page.

Vowel Chart

  • The Vowel Chart can now zoomed (with the mouse wheel), and panned (with Ctrl+Click+Drag).

Sound Generator

  • new settings page, for example to specify the sampling rate of the generated sound
  • improved support for profiles

Long-Term Average Spectrum

  • The Long-Term Average Spectrum (LTAS) is no longer synced automatically with the selection by default. The workflow is now to make a selection, and then click on Markers / Set average spectrum to selection.
  • The old behaviour, where the LTAS is automatically set when the selection changes, can be achieved by enabling the option Markers / Sync average spectrum with selection in the Markers menu, or on the Pointer & Selection settings page.
  • The LTAS overlap can new be specified on the Analyzer Settings page.

Analysis View

  • The workflow for using the Analysis View has been revised.
  • The layout and contents of the output display have been revised and improved.
  • Improved sorting options for Spectral Peaks analysis.
  • The Analysis View can now analyze the average spectra of Markers that are selected for comparison as separate items.
  • New option to analyze only content of selected Markers (and not of the current spectrum).
  • The refresh rate of the Analysis View can be set at Advanced Settings / Display / Analysis View updates/second.
  • The Analysis View control panel is now collapsible to save screen space.

File boundaries

  • When zooming to fit the current selection, the viewing rectangle will now be centered around the selection, which makes the workflow more intuitive when working with very short selections.
  • Separate recorded segments or generated sounds have their spectrogram and spectrum cleanly separated without bleeding into each other, for more accurate analysis.
  • The spectral content at the end of the files is now displayed when not recording. This improves usability of short files and very high frequency resolutions.

Vibrato Analysis

  • This feature has been revised for greater accuracy and robustness. Due to the new whole file pitch cache, the accuracy of the vibrato analysis is now independent of the current time zoom level. And the algorithm for calculating vibrato rate and extent has been improved.
  • It also has a new button to select the largest time segment that encloses the current cursor position, so that such segments can easily be selected.
  • The current vibrato cycle that encloses the cursor can optionally be highlighted.
  • New metrics for Vibrato Jitter and Vibrato Shimmer, to calculate the measure of variability/consistency for vibrato rate and extent.

Data Export

  • New command File / Export Data to open the Export Data dialog, which allows to export many items to a spreadsheet file that can be opened in Excel, Libreoffice Calc, and other programs that can read .xslx files.

Exportable items:

  • Long-term:
    • Fundamental Pitch
    • Mean pitch
    • Vibrato
    • the corresponding excerpt of the audio content can be saved into a separate audio file.
  • Short-term or aggregate:
    • Analysis View Result
    • Spectrum
    • Long-Term Average Spectrum
    • Average Spectra of selected Markers
    • Marker List

Cache Management

  • The management of temporary and cached files has been completely rewritten to be more robust and scalable.
  • The cache folder can now be manually cleared and inspected through commands on Advanced Settings / Cache Folder.


  • Multi-user editions now support floating licenses (in addition to node-locked licenses).
  • Administrative license activation for all accounts has been reviewed and improved.


  • Piano can set active slider.
  • The text on the File / Loaded file info window can now be selected and copied.

Hotfix Build 5.7.1

Based on the initial user feedback for build 5.7.0, we have fixed two issues:

  • Spectrogram sometimes disappears when starting recording
  • The lines in the EGG History and Short-term EGG view are drawn incorrectly

VoceVista Video 5.6.3

This is a patch release which fixes various bugs.


  • Fix possible crash when connecting USB devices, or when the machine wakes up from sleep.
  • Revert viewing position being moved to beginning of file when a selection is deleted.

VoceVista Video 5.6.2

VoceVista Video 5.6.2 is a service release to improve stability, performance, and fix various bugs.

New Features

  • Input Level Meter: When the app starts, the input level meter will always be off. It now has a second instance on the Recording Settings dialog, and the level meter will start when the recording settings are opened. It can also be started with a new entry “Restart Level Meter” in its context menu. Improve reliability and detection of current settings when level meter starts.
  • Multiple user accounts on one machine: The license can be activated by an admin for all user accounts that use the same computer. That was previously only possible on Windows. Now it is also possible on macOS.

VoceVista Video 5.6.0

New Features

This release focuses mainly on stability, performance, and usability. The most significant new feature is the possibility to set an upper frequency limit on the pitch detection, which makes the pitch detection much more useful for working with speech. Also, there are new presets for the Analyzer Settings to toggle between working with singing, speech, and instruments.
Another important new feature is crash recovery. This will restore all unsaved recordings after a power failure, system crash, or other unplanned program exit.
On Windows, the default audio driver is now WASAPI, which offers much smoother scrolling during recording than DirectSound.

VoceVista Video 5.4.2

New Features:

Pitch Detection Sensitivity

The Analyzer Settings page now has two entries to determine the sensitivity of the pitch detection: Minimum Clarity and Minimum Intensity. The intensity is a threshold in dB. If the incoming audio is quieter than this, it is rejected, even if it has a valid pitch. The clarity threshold is a measure of confidence that the detected pitch is valid, regardless of the volume of the incoming audio. Together, these settings can filter out background noise when processing speech, and will work together to keep audio that contains a fundamental pitch that is loud and clear enough.

Draw unfiltered spectrum

When using filters, the original, unfiltered spectrum is drawn as an outline:

unfiltered spectrum outline


Automatically install updates

New versions can now be installed with the click of one button. This should make it more convenient to keep the software up to date.

Bugs fixed:

  • Fix the line thickness of the zoomed waveform.
  • Image export dialog might be included in the exported image under some conditions.
  • Spectrum filtering could be stuck with showing the wrong content.
  • “Apply filters permanently” did not correctly use filters with custom strength values.
  • Loading and re-saving mp3 files did not work.
  • Textual cursor info on spectrum had the wrong position when “note name” was not shown.


VoceVista Video 5.4.1

This is a small service release with some bug fixes:

  • File type selector on the “Save As” dialog was invisible in some cases on macOS, which would prevent saving files as Mp3.
  • The current colormap was not refreshed when the active colormap was deleted.
  • Fix opening files on Windows File Explorer through the right-click context menu “open with VoceVista Video”
  • Fix saving edited mp3 files.

VoceVista Video 5.4.0

This release of VoceVista Video 5.4.0 has been cooking for almost a year and brings several major new features, as well as many smaller improvements and bug fixes.
This release does not yet contain documentation for the new features. We will update the user manual and add new tutorial videos for everything in the coming weeks.

VoceVista Video Pro

Vibrato Analysis

The biggest new feature in VoceVista Video Pro 5.4 is Vibrato analysis. Vibrato is a periodic fluctuation of the fundamental pitch of a singer. The vibrato analysis feature can plot the vibrato rate and extent over time, and it can show a numeric readout of the instantaneous and average values of those parameters.
Here is a video tutorial for this feature:

EGG Wavegrams

The electroglottograph (EGG) display now officially supports the EGG Wavegrams developed by Dr. Christian Herbst. Similar to how the spectrogram can visualize how the spectrum changes over time, the EGG and dEGG Wavegrams visualize how the EGG and its derivative change over time, so that the entire history can be visalized in a single image.

Improved Long Term Average Spectrum

Various bugfixes and workflow improvements were made to showing the Long Term Average Spectrum.

Marker list improvements

The theming of the marker list has been revised to give a better visual grouping of a file and its markers. Also, the workflow for selecting and managing markers has been revised and improved.

All editions (VoceVista Video Pro, VoceVista Video, Overtone Analyzer)

Real-time pitch display during playback and recording

During recording and playback, the current pitch is now shown in real time, and the detected musical note can be shown on the piano and the staff view.

Improved accuracy when tracking pitch of singing voice

When singers put a strong emphasis on their higher harmonics, the pitch tracking might pick those harmonics as the fundamental pitch, because in a mathematical sense, they might be the strongest periodic component of the sound. With the new feature prefer harmonic fundamental, the pitch tracker will find the fundamental at the base of the harmonic series, even when the higher harmonics are very strong. This makes pitch tracking for singing much more robust.

Color pitch line by frequency

In addition to having a flat color for the pitch line, this line can now be colored by frequency. The colors will repeat for each octave. This can be enabled unter Preferences / Frequency Scale / Color by Frequency. Thanks to Heidi Moss for requesting this feature.

Improved Sound Generator

The Sound Generator now has much richer simulation options, including second-order modifiers to create dynamics, and to change speed and extent of vibrato over time.
In the picture above, the vibrato rate follows a bell curve to change smoothly from 2.5 Hz to 7.5 Hz and back, while the vibrato extent follows a linear curve from 100 to 50 cent.

More audio backend options

Under Preferences / Advances Settings / Audio Performance, you can now select a new audio backend (“Backend R”) for better compatibility on some MacBook models. On Windows, this will allow to record through the “ASIO” framework, which offers very low latency on high end sound cards.

Smooth colormap interpolation

So far, all colormaps have used linear interpolation between their control points. This may cause some sharp spikes, such as in the yellow part in the middle of the colormap above. With the new “Smooth” color interpolation method, the colors flow more naturally into each other without any spikes.

 Selection Period and Frequency

For selected time ranges that are shorter than one second, the inverse of the selected period is automatically displayed as frequency. This allows to verify the period and frequency of vibrato cycles, or even individual vocal fold vibrations.

VoceVista Video 5.3.4

This is a service release to fix recording on macOS 10.12 and 10.13, which had been broken in VVV 5.3.3 due to the recent changes made to support macOS 10.15 Catalina.

If you are running VoceVista Video 5.3.3 on macOS 10.14 or 10.15, or on Windows, you don’t need to do anything.

If you still run macOS 10.12 or 10.13, please upgrade to this version VVV 5.3.4.

Also, on some specific Macbook Air models, the recording produces a distorted sound. If you experience this issue, please check out this page for a beta version and a fix.
