I've just created some packages for SpecMatch.<br>
<br>
<br>
What is it??<br>
<br>
SpecMatch can be used to adapt the sound produced by a Guitarix<br>
setting to another recorded sound.<br>
<br>
It can also be used independently of Guitarix (cf. specmatch
--help).<br>
Then you will need another convolver like the LV2 Convolution Reverb<br>
to use the produced filter. You can also use just the Python modules<br>
(e.g. from specmatch import SmoothedIR).<br>
<br>
<br>
Usage:<br>
<br>
SpecMatch needs jackd, if its not already running use qjackctl (or<br>
similar) to start jackd.<br>
<br>
SpecMatch works with project-files (extension .specmatch). On the<br>
first start a file selection window will appear enter a project
name.<br>
On subsequent launches the last selected project will be opened<br>
automatically. You can use the "Change File" button to select
another<br>
project file or create a new one (changes in projects will be<br>
auto-saved).<br>
<br>
Guitarix will be auto-started by SpecMatch (if you start Guitarix<br>
manually, you need to use the option "-p 7000" so that SpecMatch can<br>
remote-control it).<br>
<br>
Click on "Original Sound" and select a file. Press the play symbol<br>
(triangle) and set a range (for long sound files it's better to set
a<br>
small range first). The sound snipped should not be much longer than<br>
10 seconds. For stereo sounds, you can select one of the channels
(or<br>
the sum) or produce a stereo IR.<br>
<br>
Use "Recorded File" to select a recording of your Guitar (dry,
without<br>
processing), or just enter a new file name and use the "Record"<br>
button. The recording will wait (pause symbol) until there is sound<br>
(red light), and stop when there is at least 1 second of silence (if<br>
you see a scissor symbol, the input is clipping and you should lower<br>
the preamp level).<br>
<br>
Now select the convolver (amp mono chain or gx stereo chain). The<br>
stereo convolver can also load mono IR's. If you selected stereo for<br>
your original sound, the stereo convolver will be used.<br>
<br>
After "Generate IR" click the "play" button and "A <-> B" to
listen<br>
and switch between the original sound and your own processed
recording.<br>
<br>
In addition "Generate IR" sends the IR to Guitarix and activates the<br>
Convolver, so you can check the sound with your guitar. You can have<br>
quick cycles of changing Guitarix settings, producing a new IR and<br>
listening to the sound. An additional (linear) filter in front of
the<br>
convolver does not make much sense, but you can put it in front of a<br>
distortion unit.<br>
<br>
If you change the size of the IR or the FFT cutoff level (below that<br>
level it's assumed that spectral information is drowned in noise and<br>
values are interpolated or extrapolated). You can look at the plots
to<br>
find out what changes, but you should also check with your ears...<br>
<br>
The "Deploy" button lets you select a name / directory for the<br>
produced IR. It also sets the filename in the convolver, so you can<br>
define the setting with the IR included as a new Guitarix preset.<br>
