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.
As usual: 
Ciao,
