2008-05-06T13:29:00.000+02:00

Change in csound handling to enhance stability (linux).
Add videoWidth and videoHeight
Fixes to the Recorder. Male it works correctly for a sample rate of 44100 and a FPS of 30. Wav file and number of generated frames will give the exact movie length

AVSynthesis version 12_05_08

2008-05-04T10:25:00.001+02:00

For solving stability issue on Linux, the csound thread design has been changed to the use of normal Java thread, in place of the CsoundPerformanceThread class provided by csound.
Fix: refresh main frame window title after bact rendering (aka wav image recorder for creating movie).
Fix: calculate the correct rendering length when a layer has a volume curve with no points.
As the jogl version is stable, and performing well, the lwjgl version is removed from the package and the documentation.

AVSynthesis version 11_05_08

2008-05-03T07:57:00.000+02:00

Switch back to TGA file recorder. Memory consumption seems to be solved with latest device driver. Also the code based on bmp file generation was not working on some linux environment.
JOGL is at 1.1.1 level

The documentation with download link is here

AVSynthesis version 10_05_08

2008-05-02T10:03:00.001+02:00

Change the screen shot code for movie creation, as it was causing too much memory consumption. The picture file format is bitmap.
Add the possibility to use the shift key in place of the alt key for Linux environment.
Fix bug with the RMS max value display code.

After updating the ATI grahic device driver, the JOGL version is working perfectly on Vista. This version will be the reference version that will be developed further, the LWJGL being in freeze mode.

AVSynthesis on Linux

2007-12-20T22:01:00.001+01:00

Dave Phillips has made AVSynthesis working on Linux. This is not a trivial task as AVSynthesis is using third party libraries, like LWJGL and Csound. Great job Dave!

He has also produced some video demos that sounds great at http://linux-sound.org/avs-examples/

Here is a thread in the Linux audio mailing list http://lists.linuxaudio.org/pipermail/linux-audio-user/2007-December/049803.html

AVSynthesis Version 1_03_07

2007-11-18T12:28:00.000+01:00

I have just uploaded a first public version of AVSynthesis for those who want to experiment.

Instructions are here.

AVsynthesis Composition TerraFusionScape

Here is a compostion made with the last version of AVSynthesis. Sound and Visuals are rendered in real time. Csound is entirely used for sound synthesis and no samples has been used. Video quality is reduced of course for Web publishing.

Some news after a long period.

I have been busy after my PC refused to boot, and I had to quickly replace it with a laptop, pre loaded with Vista. It was in March, and XP was not an option at this time (and this is no so widely available these days). The transition was not easy as the ATI display driver for the x1700 card that equips my new laptop has no OpenGL support!

Waiting for an update, I have done some tests with Ogre3D (a C++ 3D engine) and csound (worked fine together), as well as using vvvv and OSC protocol with csound (ok too). After a while, an updated driver supporting OpenGL was released by the laptop vendor and I was pleased to use again HPKComposer. The performance are right (sufficient). Core 2 duo (1.66) and X1700 class GPU have enough power for displaying three simultaneous layers of image transformation, and for running csound in real time.

After recovering my previous environnement, I have started the development of a new software derived from HPKComposer, AVSynthesis, with the following design points in mind:

No dependency on the Eclipse frameworks, for facilitating cross-plaform distribution.
Simple and multimedia like User Interface.
Random generation of composition made of Audio Visual layers (maximum of three at any time), for ever changing runtime interpretation . The software becomes part of the composition process.

Here is a link to a document that shows some screenshots of AVSynthesis.
