 ...  wow...
i didn't think i'd see stuff this cool available open-source, already. Is
this progress, or just patent expiration?? This is sorta like having a free
pass to all those fancypants windows/mac plugins
<http://www.audioease.com/>you see in the catalogs and are never going
to buy or try unless you do it
at a loud&annoying tradeshow or music store (or in college)... the ability
to experiment, patch&try, find out about other people's uses and
ideas,...actually more like priceless...

Here's a few jconvolver-related tips:

(0) Guitarix is a really nice way of using jconvolver. Despite the name, It
doesn't break or malfunction in any way when used with a synth or sampler
:-) and very well-integrated w/ jack.

A new Fedora release is now available w/ even more
cool features (thanks Orcan!):

A room-corrected Ambisonic listening rig made with free software

This paper (presented at the Tonmeistertagung 2008) describes the setup and
calibration of a room-corrected, Do-It-Yourself Ambisonic listening rig made
of affordable hardware components and free/open-source software.

The rig comprises a Linux Audio computer with the JACK realtime sound
server, the Ardour Digital Audio Workstation, AmbDec (a state-of-the-art
two-band Ambisonic decoder with near-field compensation), and the JConv
convolution engine.

The DRC room correction software is used to obtain filter kernels to
compensate for room and speaker deficiencies.
It is shown that a determined amateur can achieve very good results using
only free software and commodity hardware in a standard domestic
environment.Presentation slides are at

Note:

>              Why Ambisonics?

Free software is only fun with free codecs, free

algorithms and free exchange of information.

 All major Ambisonic patents have now expired,

   and there is a huge academic and hobbyist

community of enthusiasts, plus a rich supply of

   freely available code and documentation.

     And: it sounds good and scales well.
