Hi guys, I've started/hacked a small project called GuitarSynth. It is
meant as a playfield for exploring pitchdetection and synthesis for
Guitar, since I'm a guitarist. You can get on Github (git clone
https://github.com/geraldmwangi/GuitarSynth.git).
Its really basic but its fun to play with. It take an audio signal (your
guitar) extracts the fundamental pitch and drives some wavetable synths.
Feel free to manipulate it, I'll be happy to grant people write access
to the repo.
Btw on IRC my Nick is JimsonDrift, the name of my band (see
www.jimson-drift.de).
Cheers Gerald

Looks like an interesting and fun tool.
I had to add this library:
apt-get install libclam-qtmonitors-dev
- I built the code but when I run I get a segfault:

I'll look into that. I used clam since it had prettier knobs but dropped
it again, as it isn't developed anymore (?)

Clam dep is removed. Can you compile it and run it again? Set jack
samplerate to 44100 and Periods to 512 (my settings).

Looks like an interesting and fun tool.
I had to add this library:
apt-get install libclam-qtmonitors-dev
- I built the code but when I run I get a

New subject: [LAU] GuitarSynth
Hello,
I also met a hang with GuitarSynth.
I use fedora 21 64. I compiled aubio from sources (the one on fedora is
too old).
There is no stack trace in gdb, but there are some messages at startup:
Samplerate 48000 Buffersize 256
QObject::connect: No such slot GSEngine::setInputGain(int) in
../mainwindow.cpp:62
QObject::connect: (sender name: 'InputVol')
QObject::connect: No such slot GSEngine::setOutputGain(int) in
../mainwindow.cpp:64
QObject::connect: (sender name: 'OutputVol')
[New Thread 0x7fffe347d700 (LWP 23722)]

Thanks, I can see and hear GuitarSynth now even with the following settings:
creating alsa driver ...
hw:PCH,0|hw:PCH,0|1024|2|48000|0|0|nomon|swmeter|-|32bit
configuring for 48000Hz, period = 1024 frames (21.3 ms), buffer = 2 periods
It would be handy to be able to extend the height of the UI.
Already got a serious "bit's and bleeps" session going on without even
trying ;-) Looking forward to rinsing this out.
Cheers

I had to add this library:

Hi guys, I've started/hacked a small project
called GuitarSynth. It is
meant as a playfield for exploring pitchdetection and synthesis for
Guitar, since I'm a guitarist. You can get on Github (git clone
https://github.com/geraldmwangi/GuitarSynth.git).
Its really basic but its fun to play with. It take an audio signal (your
guitar) extracts the fundamental pitch and drives some wavetable synths.
Feel free to manipulate it, I'll be happy to grant people write access
to the repo.
Btw on IRC my Nick is JimsonDrift, the name of my band (see
www.jimson-drift.de).
Cheers Gerald

This looks like you should go for Qt5 instead of Qt4.

Yes thats true. I built it on Ubuntu 14.04 and on Arch Linux both with qt5.
which distro are you on?

if you fix line 21 in file synthcontrol.h from
#include <QtWidgets/QDial>
to
#include <QDial>
your code will compile with Qt4 as well.
But btw. I got some serious compiler warnings. I recommend to carefully
fix them too.

Hi Guido, thanks for the patch. I applied and pushed it up. Haven't
tested it though.
I'm thinking of using falktx's DPF lib to make GuitarSynth a plugin.
Will deal with that on friday. Meanwhile,
can someone point me to a paper or some code on polyphonic pitch
detection or even blind source separation?

Would the pitch detection be easier with a hex pickup with individual

But I'm also rather interested multipitch out of one signal. It's just

Polyphonic pitch detection is much more involved and requires more advanced
algorithms which are computationally intensive and thus hard to perform in
real-time.
Commercial closed-source software like Melodyne can do this, at least in
off-line processing. AFAICT, the latest Melodyne versions also do some
real-time processing, but I haven't used Melodyne for some time and so I
don't know how well that works.
I'm not sure either whether there are any good open-source codes for this
available yet, maybe others can provide corresponding links. But here are
some relevant answers from Stackoverflow and Stackexchange:
http://stackoverflow.com/questions/9613768/multiple-pitch-detection-fft-or-…
http://dsp.stackexchange.com/questions/11433/polyphonic-detection-mulit-pit…
Also, here's an interesting recent DAFx paper on doing polyphonic pitch
detection using autocorrelation:
http://www.dafx14.fau.de/papers/dafx14_sebastian_kraft_polyphonic_pitch_det…
And then there's the work of Anssi Klapuri and others at Tampere University:
http://www.cs.tut.fi/~klap/iiro/
Also, there are algorithms for doing spectrum estimation such as filter
diagonalization methods (FDM) and the classical Prony algorithm, but due to
their complexity these probably aren't well-suited for real-time processing
either (the Prony algorithm also suffers from numerical instabilities
IIRC), and you still have to do the partitioning of the overtone series
afterwards.
There's surely more, but that's what I could find with a quick Google
search or remember from the top of my head.

Audio-to-midi polyphonic pitch converter.
It is a real riot! Super fun to try.
I was able to play polyphonic guitar chords and have it come out
as midi, for example piano.
With velocity detection. And anti-retriggering.
There is one drawback. Latency.
For FFT to distinguish among notes it needs a certain amount of
samples in a block. More samples per block for lower notes.
On guitar it was just sorta kinda usable, but fun.
To reduce latency I even tried putting the guitar through a standard
time-domain pitch shifter (up one octave) and then into the detector.
Not bad, so so.
Question: I tried a demo product which did polyphony, with similar
latency as my app, which claimed to have a full version with
near-zero latency.
Is this actually possible?
And with properly timed chord notes (not high notes sounding
before low notes ie lower latency for higher notes)?
Related question:
Albert (and list), I am desperately searching for a pitch shifting
phase-vocoder audio plugin with lower latency than FFT.
I have read about wavelets for a long time.
They are said to be better for this than FFT.
Hard to find real working examples except in commercial.
In PD, there is a wavelet pitch shifter (I think in PD extended)
but it is *broken*
I emailed the list but got no reply except to contact the author,
which I haven't done yet.
Are wavelets good for polyphonic pitch detection too?
Can anyone shed more light on them in this context?
Thanks for the links Albert, bookmarked and will check them out.

Ciao,
OK Albert, I uploaded the source of my polyphonic guitar synth to:
https://github.com/terminator356/polyguitsynth
The latest version was written in Borland C++ Builder around 2000.
The source uses a few of my 'hidden continuous borderless mouse'
controls which I discussed in another current LAD thread concerning
'user eXperience in Linux'.
You won't be able to actually build the source without those
controls' sources, which I did not upload :-(
However, I included the finished executable !
And... it *runs* under Wine !
:-)
(Gotta love Wine, the older the program, the better it is.)
Inspiration for the OP I hope.
Try it, both to see how the program works and to see how my
'hidden continuous borderless mouse' controls work.
(Press the mouse inside any of the edit boxes and then move the
mouse, observe the mouse hides and the edit value rolls on and on...)
The source does include the actual DSP library I used.
It is the GNU2 licensed 'libdsp' from Philippe Strauss.
The program includes the ability to use the PC keyboard
as a music keyboard, hence the map on the right.
[Fons:] Yeah, believe it or not it works best with *dead* guitar strings
and the guitar's tone knob all the way down.
Don't want too many rich guitar string harmonics in there!
Given that, it works kinda OK.
Fons do you have any insight into wavelets and how they might
be better for lower latency pitch detection than FFT?
Cheers.
Tim.

I don't think they will allow you to have better latency
if all other aspects of performance are kept equal.
Don't expect magic from wavelets - they can't provide
information that isn't there. What they allow you to do
is modify the tradeoff between resolution in time and
frequency. But the product of the two is limited by
the 'uncertaintly principle' in all cases: better
resolution in time means less resolution in frequency
and vice versa.
There is no way to break this limit *unless* you make
assumptions about the signal to be detected and accept
failure if these are not valid. Human hearing seems to
do this. In the case of a guitar signal there are some
valid assumptions, e.g. the maximum number of notes
and the typical exponential decay of their envelope.
For the last ten years or so, a new technique called
'compressive sensing' has been a hot topic in DSP.
It is being used to do all sorts of things that at
first sight seem impossible, such as recovering a
signal from random samples well below the Nyquist
rate. It again depends on making certain assumptions
about the analysed signal, in this case that there
exists a 'sparse' representation of it.
The whole theory behind CS is a bit counter-intuitive
but mathematically perfectly sound. I'm pretty sure
it will lead to some new ways to do pitch detection.

The purpose there was to shift the guitar up one octave before
it goes into the polyphonic detector, so that I could reduce
the number of FFT bins required and therefore reduce latency.
It worked better, kind of OK, but if you know standard
time-domain SOLA pitch shifters, they leave artifacts in the sound,
so it's not an ideal solution.
A nice frequency-domain pitch shifter would be better - very little
artifacts in the sound - but these shifters have large latency,
so that cancels the purpose of this because time-domain
SOLA shifters have very little latency, but just the artifacts.

"dead" guitar strings in water. As

Aw jeez, sad situation, buy a new set of strings, eh :-(
If you lived in my city I'd give you a pack!
Yeah I tried boiling them a few times long ago.
All that really seemed to do was bring out the rust even more!
I've always believed it's not so much the dirt or oxidation on the
string which is the problem:
That simply makes it appear like a slightly thicker string and thus
the tuning changes slightly. Most of the dirt can be removed.
The real problem is the dozens of small 'cuts' along the string length
that are accumulated over time from bending, or just playing, against
metal frets. This produces horrible overtones. The single fundamental
frequency of a given fret position begins to 'split' into two or more
fundamental frequencies. Ugly.
Just a side 'note': A tip for players out there:
There is a tendency to think that one should adjust the pickup as close
as possible to the strings without touching them, for maximum output.
Seems reasonable right?
But no, don't do that. Because the strings then sit in a less linear
portion of the magnetic field - on the 'down swing' they are attracted
much more to the pickup magnet than on the 'up swing'.
The result is mechanical nonlinear string motion, resulting in...
split fundamental frequencies.
The effect is striking. You can hear it without even plugging the guitar in.
As you adjust the pickup ever higher, and pluck the strings, you can
hear the horrible overtones from the frequency splitting.
It's really gross sounding. So be careful.
Enjoy your day :-)

Interesting note, you must have ears if you can hear the overtones that

I adjust the highs of my single coils depending to what I do. I anyway

to the twelfth fret (IOW around the thirteenth and fifteens fret),
because a single coil close to the neck then produces an unique sound.
Indeed, when playing a guitar I seldom want the noise caused by to high
coils, but when recording it to make a sampler sound it's wanted for
one or he other tone, "dirt" makes a sound sample sound more natural.
The day before I adjusted action and intonation. Too funny, just one
day, perhaps caused by another temperature of the room and the
intonation that was nearly perfect the day before, wasn't perfect
anymore. I guess intonation of guitars could become a serious issue for
converters. I place value on a good intonation, but if the tuning is
perfect when playing open and for the twelfth fret, the tuning for the
frets between open and twelfth fret still could be disastrous. I only
can fit the intonation to the way I play my guitar, if somebody else
should prefer to play chords and scales in other positions, the
intonation likely is broken. However, the e guitar at least has a
relatively good intonation. My classical guitar has got a very
"unique", "odd" intonation ;) and there's no action to adjust it.

well the goal is to not that dependent on the frequencies being played,
but rather on the timbre/frequency envelope of the instrument. This way
not the current tuning would be the serious issue,

Hi Gerald,

Bend, slide, hammer on, pull off, muted, fingertip, plectrum or even
different kinds of strings, 09 - ... nickle round wound, 10 - ... steel
flat wound etc.? Ok, if you don't mix the original guitar signal with
the converted signal/MIDI instrument, you don't need to mute and perhaps
you can resist to play a mix of fingertip and plectrum, but you likely
will slide, hammer on and pull off, not only when playing
monophonic, but also when playing chords. IOW even if your software can
learn what the "main" timbre on different strings and octaves for
different tones is, does it work for guitar playing techniques or does
the guitarist need to play the guitar in a keyboard style?
A simple example, without or even with compressor, play
g string - fret 3 and slide to fret 5, hold the tone
d string - fret 3 and slide to fret 5, hammer on and pull off fret 7
do the same, but instead of fret 3, start somewhere behind fret 12, at
least without compression already the loudness could become an issue,
while you still clearly hear changing frequencies.
That were just 2 tones.
Now play
e string - fret 3 hold the tone
b string - fret 3 hammer on and pull off fret 5
g string - fret 4 hold the tone
d string - fret 5 hold the tone
If you like you could slide the g chord to an a chord before you do the
hammering. Do this on different positions, e.g. play a c chord this way.
Perhaps I misunderstand what "timbre/frequency envelope" is.

Hi Ralf,
this works pretty good with my lowpass->rectify->aubio pitch detection.
What I want to work on (once GuitarSynth is ported to DPF) is a
source-filter analysis (see U Zölzer: DAFX) to extract the spectral
envelope (timbre) of the guitar. As Zölzer putts it, it is then possible
to obtain a neutral frequency analysis, that just the tones/frequencies
without their attenuation due to playing technique. This is done simply
by dividing the FFT'd input signal by the envelope.
I think that should be done before the pitch detection. And anyway I
want to convolve/multiply the envelope with the synths (as an option in
the GUI). Then GuitarSynth will really be a guitar synth ;)

This LADSPA plugin

will do a crude job of that, if you want to try it out. It uses a
cepstral envelope estimator.

What I really mean is that it wasn't written for use in a specific
application, so it hasn't had any real testing or evaluation. The
purpose of it is to be a handy tool that you can use to figure out
whether this sort of transformation makes a difference to your feature
extractor, rather than necessarily to be the final implementation you'd
actually put in the extractor.

Hi Ralf,
this works pretty good with my lowpass->rectify->aubio pitch detection.
What I want to work on (once GuitarSynth is ported to DPF) is a
source-filter analysis (see U Zölzer: DAFX) to extract the spectral
envelope (timbre) of the guitar. As Zölzer putts it, it is then
possible to obtain a neutral frequency analysis, that just the
tones/frequencies without their attenuation due to playing technique.
This is done simply by dividing the FFT'd input signal by the envelope.
I think that should be done before the pitch detection. And anyway I
want to convolve/multiply the envelope with the synths (as an option in
the GUI). Then GuitarSynth will really be a guitar synth ;)

I only build your software until now, since I don't had/have time to
test it at the moment.
But I'll test latest pull from git ASAP.
At the moment I only can confirm, that I was able to launch this
versions and they showed up in jackd :):

Did you already release a git version that is able to handle polyphony?
My apologies for not testing it. I promise I'll do ASAP.
Your project is cool, very interesting. I don't like to pay for a hex
pickup that needs to be installed to my vintage guitar and that in
addition needs a stand alone synth to convert to MIDI. I would like
some kind of converter that is able to e.g. use my Oberheim
Matrix-1000, without damaging my guitar. The Matrix-1000 has got a
guitar mode! It's one of my best synth, but I try to use it as less as
possible, since if ever a Curtis/CEM chip should get broken, there's no
chance for me to pay for a spare part.

No problem.
I wish I had polyphony!! It's only monophone since i'm not an expert on
the matter.
Right now i'm converting it into a lv2 plugin (actually lv2,vst, au by
virtue of falktx's DPF).
I have no idea when and how (well not quite how) i'll achieve polyphony,
probably never.
But alot of things can be learnt on the way (source-filter separation,
non-neg matrix factorization, wavelets). Not to mention the code from
the people on the list/IRC (thanks guys). It's my friday evenings
hacking project, after the kids are in bed. And it's fun.

Well, I found that rectifying the signal before aubio pitch detection
improves the result.
This is because the time resolution is divided by 2 and due to
uncertainity the frequency resolution is doubled. Furthermore the input
is lowpassed at 6khz to reduce the effect plektrum and nail picking,
which generate high frequencies.
I assume that some better (freq-dependent) rectifying procedure could
split the harmonic structure of the strings further apart in
freq-domain, that is making the time/freq-resolution frequency dependent:
low frequencies<->high freq resolution
high frequencies<-> low freq res.
this could be achieved, i believe with wavelets.
Thats the first step.
Following step: Now imagine the frequencies as being samples in
frequency domain:
The samplingrate is a function the frequency, and get this function from
the wavelets in the first step.
With the Constant-Q-Transformation, one could map this function to a
constant function, and thus the frequency domain to a domain in which
all harmonic combs have equal distances between their partials, but
different locations.
It should be easy then to locate the combes, then do the inverse
Constant-Q to get the fundamentals.
..but its probably b*** sh** ;)

Thanks Albert,
I've already come across some of the links you posted, the otherones
I'll checkout.
I've read about non-negative matrix factorization stft basis functions
and some iterative cancellation procedures. Not sure which path to take.

Nice to play around. Fast pitch detection and reliable in most cases. The performance
drops a lot when using the 6th string though.
Nevertheless, good work Gerald!

Hi guys, I've started/hacked a small project called GuitarSynth. It is
meant as a playfield for exploring pitchdetection and synthesis for
Guitar, since I'm a guitarist. You can get on Github (git clone
https://github.com/geraldmwangi/GuitarSynth.git
<https://github.com/geraldmwangi/GuitarSynth.git>).
Its really basic but its fun to play with. It take an audio signal (your
guitar) extracts the fundamental pitch and drives some wavetable synths.
Feel free to manipulate it, I'll be happy to grant people write access
to the repo.
Btw on IRC my Nick is JimsonDrift, the name of my band (see
www.jimson-drift.de <http://www.jimson-drift.de/>).
Cheers Gerald

Thanks. The pitch detection is done by aubio library, but I rectify the
signal before since that stabilizes the detection.
By 'the 6th string' I assume you mean the lower pitched E string? Thats
due to the longer waveform of lower frequencies which would need more
frames per period to be detected. Low frequencies are a problem if the
algorithm detects only the fundamental freq and not the harmonic comb (I
dont know if its the case with aubio' yinfft algo). I had better results
with a harmonic comb algorithm at lower freq, but I used the CLAM Audio
suit for that. Sadly CLAM hasn't been updated for sometime (since 2010),
so I scraped it. Maybe I'll extract the relevant parts of CLAM for
GuitarSynth.
