Hello all, Some updates and new things on my webpages. First official release of jconv. Jconv is a command line jack client performing FFT-based convolution using a mix of up to five partition sizes, small ones at the start of the IR, and building up to the optimum size further on. It allows zero-delay convolution with moderate CPU load. Jconv uses the multi-threaded convolution engine developed for use in Aella, a convolution engine optimised for reverb processing that is nearing completion. Main features of jconv: - Any convolution matrix up 64 by 64, as long as your CPU(s) can take it. - Allows to trade off processing delay to CPU load, and remains efficient even when configured for zero delay. - Reads the same config files as Jace which it will eventually replace. The beta version released two months ago to some volunteers contained a bug discovered and patched by Martin Rumori. It did not affect configurations using independent 1-to-1 convolutions, only matrix operations. Update of Ambdec Some small changes and bugfixes. The configuration format now also permits the use of mixed-order de- coders (2nd order horizontal, 1st order vertical). Manual updated. TetraProc / TetraCal. Both are ready and have been used for real Ambisonic recordings, but release of TetraCal awaits a required update of Aliki, and completion of the manual that describes the calibration procedure. If you want to use Core Sound's TetraMic with TetraProc this is possible today. I signed an NDA with Core Sound giving me access to the impulse response measurements performed by Core Sound on each mic. Given the serial number, I can process these using TetraCal and provide a matching config file for TetraProc. You can see some examples of this on the updated screenshots page for TetraProc.
