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
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
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).
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.

Follie! Follie! Delirio vano è questo !
