On behalf of the guitarix team I'm proud to announce

Guitarix Version 0.11

Guitarix is a simple Linux Rock Guitar amplifier and is designed
to achieve nice thrash/metal/rock/blues guitar sounds.
Guitarix uses the Jack Audio Connection Kit as its audio backend
and brings to the jack audio graph a mono amplifier input/output port,
and a FX mono input with two (stereo) output ports.

Guitarix provides a jack midi input port to connect a midi controller
(midi learn) and a (3 channel) jack midi output port, feed by a
(scalable) mix of the tuner and a beat-detector.

Release 0.11.0 comes with following changes :

Users visible changes:

- new version of the impulse response parameter editor. You can
now graphically define a gain line to be applied to the IR data,
e.g. emphasize a part of the early reflections or damping the
reverb tail to make it fit to your guitar sound.

- the multi-line distortion effect now has 4 frequency bands and
is better optimized

- fix regression from version 0.10.0: now the default preset file is
created again if it doesn't exist (e.g. in new installations).

Changes that might be interesting for Developers:

We put the Guitarix widgets into a library, with the goal of
making them usable independently from Guitarix. You can build
it as shared library and there's a c++ (gtkmm) wrapper, a python
wrapper and glade support. Check it out and look for examples
in those directories, or just build a nice looking display with the
glade editor, and of course ask in our Guitarix forum (it's still

As a side note, Guitarix is now in debian (unstable), of course at
the moment still the previous version 0.10.

have fun

For capture, guitarix uses the great 'jack_capture'
(version >= 0.9.30) written by Kjetil S. Matheussen.
If you don't have it installed,
you can look here:


For extra Impulse Responses, guitarix uses the
zita-convolver library, and,
for up/down sampling we use zita-resampler,
both written by Fons Adriaensen.
If you don't have it installed, get it here:


We use the marvellous faust compiler to build the amp and effects and will say
thanks to

: Julius Smith

: Albert Graef

: Yann Orlary

For faust users :

All used Faust dsp files are included in /guitarix/src/faust,
the resulting cc files are in /guitarix/src/faust-generated
The tools we use to convert (post-processing and plot)
the resulting faust cpp files to the needed include format,
stay in the /guitarix/tools directory.
