How to start Sonogram (Juli 2009):
A short note because many people have questions concerning how to start Sonogram. First of all before you can start Sonogram, you must install Java and optional Java3D on your computer like described below. There are two ways to start Sonogram: The simplest way is to press the Sonogram WebStart button at the end of the page, sonogram should start automatically from this webpage. The Second way is to download the program from the sourceforge website where also the source code is available.

iPhone Version of Sonogram (November 2008):
Yes, i invested the 79€ and am now paying member of the Apple Developer Connection and official iPhone Developer with the license to sold iPhone software via the iTunes-Store. And yes, this means that the iPhone version of this fine algorithm collection will coast money. Following a specification:

1. •The Name will be changed. My idea is to name it simple "iPhone Signal Analyser"
   

2. •All algorithms run as realtime analyser application.
   

3. •It should at least have the possibility to switch between this signal analysis algorithms: Waveform, Spectrum, Spectogram/Sonogram, LPC-Spectrum, LPC-Prediction-Error, Autocorrelation, Cepstrum, Wavelet-Transformation?)
   

4. •Use the Microphone as well as the acceleration-Sensor for the real time analysis.
   

5. •Perhaps it is possible to implement the 3D-Spectogram aka. Perspectogram in  OpenGL ES.
   

6. •Develop a nice and recognizable Icon for the tool and make a smart design with the same well known colors form Sonogram.
   

7. •Write a software documentation which includes as much as possible formulas from the algorithms including there derivation.
   

New Version Released (September 2007):
Due private/familiar restrictions last time, the release which i developed the last six months will be published only now. The new version fixes many Java Bugs and brings an extended anti aliased 3D Perspectogram engine. Apart from the Java Runtime (at least in version 1.6) it is strongly recommended to install the newest Java3D and JMF extensions in order to use all the 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. Sonogram can be started directely via the WebStart button below and runs on any Operating System (Windows, MacOSX, Linux/Unix). Version changes in detail:

1. •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).
   

2. •Improved anti aliased 3d Perspectogram engine with coordinate system, rotation effect, point cloud...
   

3. •Most of the dialog, tooltip and GUI element text labels are revised and rewritten.
   

4. •Feedback message system for bug report and information exchange.
   

5. •Rewritten pitch tracking algorithm.
   

6. •Smarter design of the whole GUI.
   

7. •Java 6 ready.
   
   

Start Sonogram via Java WebStart (July 2003):
The ongoing builds 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.

The olympic games startet this summer. After the summer the winter will come fast and heating will be another interessting topic. There are many people interessted in design and print solutions.
