This new major release fixes many Java bugs in the GUI and the logarithm frequency scale and gives the application an overall performance boost. The new features are in detail:

- Added a welcome screen with basic instructions what Sonogram is and how to get a quick first glance of the programm. The welcome screen will be shown when the application starts first time.

- Added a floating information window in the main sonogram which shows the amplitude, frequency, time and level under the mouse.

- The logarithm frequency-scale was rewritten and became like the image smoothing functions a tolbar-button in the main window.

- The single spektrum view in the main window was rewritten and shows now a smarter spektrum image.

- The - Whole GUI was over-worked and the application startup procedure became like the image painting routines a strong a performance boost. The design became a facelift.

It analyses sound and speech signals with the methods of the "Fourier Tranformation" (FFT), "Linear Prediction Analyse" (LPC), "Cepstrum Analyse" and the "Wavelet transformation". It was able to open the most common audio and video file formats and is written in Java2, so it should run on any platform where Java2 is avaliable. Sonograms main goal is to be a speech recognizer, which will be implemented in next time. It requires the "Java Madia Framework" library which is avaliable for Windows, Unix/Linux.

Macintosh OS-X users do not need this librarys and can launch the program by clicking on the program file.It was sucessful tested on any platform of Windows, on Solaris 2.6, Linux, and on Mac-OS-X. The build in three dimensional surface plot representation requires the Java3D library which is not avalible for the Macintosh maschines. Sonogram runs without the Java3D libs, but then the 3D surfaceplots will not be avaliable.

Sonogram is free for non comercial and research purposes.
