If Jack gives problems try portaudio backend with the "-b portaudio" option.
In the next release we will default to portaudio backend.
The CLAM project is pleased to announce the first
stable release of
Chordata.

When I want to choose another song while one is playing, it blocks and
(in most cases) crashes JACK (jackd version 0.116.2). Also, I tried playing found chords on guitar and it
seems to me that
displayed chords are one semitone lower than the sound that is playing,
but maybe just I didn't tune guitar right (can't find tuner right now :)).
Also a bug which can be workarounded. We are not using any samplerate
conversion. The algorigthm is tuned to run at 44100 as most wave files. Jack
might have been configured to run with 48000 so you are probably hearing the
song a semitone higher than it is. Portaudio backend fixes the output
samplerate to 44100.
Other than that, some changes are needed for
compilation on Arch linux,
so a little tutorial follows:
I checked out whole CLAM svn (svn co http://clam-project.org/clam/trunk
clam). First compile clam with scons and scons install. This goes
without problems.
Next, compile NetworkEditor. If you just run scons you+ll get "undefined
interface" error. To solve that, in some files line:
#include <QtDesigner/QDesignerCustomWidgetInterface>
needs to be replaced with:
#include <QDesignerCustomWidgetInterface>
This has to be done for the following files:
src/clamWidgetsPlugin/CLAMWidgets.hxx
src/clamWidgetsPlugin/ChordRankingPlugin.hxx
src/clamWidgetsPlugin/ControlSurfaceWidgetPlugin.hxx
src/clamWidgetsPlugin/KeySpacePlugin.hxx
src/clamWidgetsPlugin/LPModelViewPlugin.hxx
src/clamWidgetsPlugin/MelCepstrumViewPlugin.hxx
src/clamWidgetsPlugin/MelSpectrumViewPlugin.hxx
src/clamWidgetsPlugin/OscilloscopePlugin.hxx
src/clamWidgetsPlugin/PeakViewPlugin.hxx
src/clamWidgetsPlugin/PixmapWidgetsPlugin.hxx
src/clamWidgetsPlugin/PolarChromaPeaksPlugin.hxx
src/clamWidgetsPlugin/ProgressControlWidgetPlugin.hxx
src/clamWidgetsPlugin/QFirstPersonPlugin.hxx
src/clamWidgetsPlugin/QSynthKnobPlugin.hxx
src/clamWidgetsPlugin/SegmentationViewPlugin.hxx
src/clamWidgetsPlugin/SpectrogramPlugin.hxx
src/clamWidgetsPlugin/SpectrumViewPlugin.hxx
src/clamWidgetsPlugin/TonnetzPlugin.hxx
src/clamWidgetsPlugin/VumeterPlugin.hxx
This changes could be done with following command (it all has to be in
one line):
for i in `grep -R -l "<QtDesigner/QDesignerCustomWidgetInterface>"
*|grep hxx|grep -v .svn`; do sed -s
"s/<QtDesigner\/QDesignerCustomWidgetInterface>/<QDesignerCustomWidgetInter
face>/" $i > tmp_file; mv tmp_file $i; echo
$i ;done
Bear in mind that this could be done much prettier and easier, but I'm
not an expert :) - run this command from NetworkEditor directory and it
should do it.
Please try to uncomment lines 418 and 419 of CLAM/scons/sconstools/qt4,py
Some qt versions have no valid pc files for QtDesigner modules
After that, NetworkEditor should compile without
problems (scons && sudo
scons install).
Before building Chordata, you need to run ldconfig as a root.
In SConstruct file in chordata directory, you need to add two paths:
where chordata will be installed and where is CLAM installed. CLAM is,
by default, installed in /usr/local, so you can also put that for prefix
(third parameter in lines 7 and 8).
Cheers!
Igor
