Hello all,
Updates of jconv, now called jconvolver, and the zita-convolver
library are available on the usual place:
<http://www.kokkinizita.net/linuxaudio/downloads>/
The new zita-convolver is API-compatible to the previous
release but not binary compatible. If you have any code
using it please recompile.
Release notes for jconvolver and fconvolver 0.8.4
-------------------------------------------------
Jconvolver is a real-time convolution engine. It
can execute up to a 64 by 64 convolution matrix
(i.e. 4096 simultaneous convolutions) as long as
your CPU(s) can handle the load. It is designed
to be efficient also for sparse (e.g. diagonal)
matrices. Unused matrix elements do not take
any CPU time.
In contrast to e.g. BruteFir, jconvolver uses
multiple partition sizes, small ones at the start
of the impulse response and progressively longer
ones for the rest. This allows it provide both
zero processing delay while still remaining
efficient in CPU use.
Fconvolver performs the same processing on files
instead of real-time.
For this relaese the package and the binaries
have been renamed to avoid a conflict with an
existing 'jconv' package (related to the Japanese
language).
Functionally this version is identical to jconv
0.8.0. See README.CONFIG for the syntax of the
config files. Since 0.8.0 it has been possible
to name and connect the Jack ports. The related
commands have been added to README.CONFIG.
Jconvolver will work with libzita-convolver 1.0.0,
but upgrading to 2.0.0 is recommended. Note that
if you update the library you have to recompile
this package.
NOTE: Jconvolver will normally not work correctly
when used with Jack's freewheeling mode, e.g. when
exporting in Ardour. It _could_ actually work when
used on a single processor system, but don't rely
on this. This release of jconvolver will print a
warning when freewheel mode is entered.
The 'mkwavex' utility from previous versions has
been replaced by 'makemulti' which offers some more
options.
Enjoy !

Fons, trying it out now, and get this. (Gentoo64bit jack 0.118.1
zita-convolver-2.0.0) Which user error would this be?

Please check if you're not mixing up old and new
versions somehow - this looks like it.

Fons, well spotted. I'd left an old Zita header behind when i cleaned
everything out.
Works ok now, and apologies for the unneccessary noise.

Hi Fons
Thanks for the update, build and run fine here on debian/sid,
I only need to modify the makefile (add DESTDIR and change path) to
build my deb packets.

when building zita-convolver-2.0.0 on x86_64 i got an error.
zita-convolver.cc:1: error: CPU you selected does not support x86-64
instruction set
i suggest using -march=native as default

My wrong. The line
CPPFLAGS += -march=i686
should have been commented out, it's for my local use.
i suggest using -march=native as default
Thanks, good idea, will fix this.

Hi,
The attached patch allows paths and filenames to contain spaces. It's
not particularly efficient, compact or generic, but it works for the
purpose.
