Sonogram Visible Speech
new version released
(you see here a temporary Homepage only with information about Sonogram)

New Version 2.80 (October 2006):
Due private/familiar restrictions last time, the new release which i developed the last six months will be published only now. The new version fixes many Java Bugs and brings an new extended anti aliased 3D Perspectogram engine. Apart from the Java Runtime (at least in version 1.5) it is strongly recommended to install the newest Java3D and JMF  extensions in order to use all the new features. Sonogram runs without Java3D and JMF but generating Perspectograms and playing sounds files will not be possible without these extensions. Next releases will only be shared via WebStart and minor changes will not be announced explicitly on this page. The new version can be started directely via the WebStart button below and runs on any Operating System (Windows, MacOSX, Linux/Unix). Version changes in detail:

  • Many many bugfixes in the core Java code  (rendering, display, windowing...) and all bugs reported in the Sourceforge bug tracking area are fixed (thanks for all the bug reports).
  • New improved anti aliased 3d Perspectogram engine with coordinate system, rotation effect, point cloud...
  • Most of the dialog, tooltip and GUI element text labels are revised and rewritten.
  • Feedback message system for bug report and information exchange.
  • Improved rewritten pitch tracking algorithm.
  • Smarter design of the whole GUI.
  • Java 6 ready.

Sonogram goes Open Source:
The sources of Sonogram are opened via Sourceforge and I'm looking for a small Developer Group (Signal analysis experts and Java programmers) so Sonogram can evolve further... A new web page with more detailed information is in preparation and will be available soon. Sonogram can be downloaded from the Sonogram open source page. To get a short impression of Sonogram Visible Speech start it via WebStart and choose "open remote Network File" from the file menu and press OK with the default file. After the spectrum is calculated press "arrange windows" from the options menu. You can now zoom in and generate the three dimensional Perspectogram.

Start Sonogram via Java WebStart:
The newest nightly build of Sonogram can be started directly via Java WebStart with the button below. Please note that the next version releases will only be distributed via Java WebStart and i will only use the WebStart platform to brand new versions. Downloads from Sourceforge will be definitely outdated next time and i will not announce any minor  version changes here on this web page. New releases will be shared and updated to the user clients automatically in this way via WebStart. Sonogram requires at least a Java Runtime in version 1.5. It is strongly recommended to install Java3D and JMF in order to use all the newest fancy features of Sonogram.

Note:
This is the first open source release of Sonogram. We have put a lot of effort into testing and debug this release, but of course the software may have some teething problems. Please help us to improve the software submitting bug reports to the Sonogram open source page in the bug tracking area. Sonogram itself includes a feedback message system where bug reports can be send immediately out of the application.
