Hi to all!
First post to this list :) and I will use it to present small project
I've been working on.
VocProc is a real time JACK application for vocal processing including
pitch shifting, automatic pitch correction and vocoder.
It is basically the same thing as fons' jretune or Tom's autotalent. I
wanted that functionality but at that time fons didn't made it and I
wasn't aware of autotalent. So I made it myself and decided to release
it. I have not tried any of the above for now, so I cannot say
anything about sound quality differences.
I made a working version of VocProc some time ago, but now finally
found some time to clean the code and prepare it to be released.
You can grab the code at:
http://hyperglitch.com/dev/VocProc
Currently, code was only tested and compiled on my computer (Arch
Linux, fftw-3.2.2, Qt4.5) and it works OK (for me).
Any feedback and bug reports are appreciated.
Cheers!
Igor

Thanks for mentioning jretune. I haven't noticed this, but just asked
Fons for a copy.
Autotalent is completely unusable, the artefacts are just too obvious.

The "corrected" version ruins your whole production. ;)
I tried VocProc, it's less critical, but it's a little hard to find
suitable settings for threshold and attack.
it. I have not tried any of the above for now, so I

What I hear for now: It's better than autotalent, but I'm waiting for
jretune to test. The idea of selecting the correct notes via toggle
buttons as done in jretune is good, it's the same as in autotune.
Like all stand-alone jack tools, it's usability hell. Starting and
wiring a tool sucks, the settings aren't saved in the session and so on.
This should clearly be a LV2 plugin. (the whole issue becomes obvious
when you think of mixing twelve vocal tracks)
VocProc also connects to physical ins/out at startup. This is annoying.
It's a typical post-production tool, so given that I'm already annoyed
by manually wiring it as an Insert inside ardour, I'll first have to
remove VocProc's physical IO to get the routing right. It doesn't make
sense at all to connect anything at startup.
Next: VocProc changes the volume. At Gain=0, it's off, which is weird. A
0dB gain means "no additional boost", but not off. Ok, so I tried
Gain=1, which makes the output louder than the input.
This isn't crucial, but it's not common. I don't want to alter a track's
volume just because I added pitch correction.
So plenty of room for improvements. ;)

easy, man. it's the first public release, and it sez oh-dot-twelve :)
which means some-way-to-go-to-shrinkwrapping.
i'm sure the author would be delighted to have your feedback in a
slightly more diplomatic tone. because you do have a point...

Thanks for comments and suggestions. I agree with you about things you
mentioned. Till now I mostly used it for fun and not in real
production so I didn't came upon these problems. But it is still in
very early stage of development so..
I started writing it as a standalone JACK client because I wanted to
write it as soon as possible without messing up with specifications. I
just took some code from Faust project that instantly gave me GUI and
JACK interface.
I have actually already started porting it to LV2 (if started can be
described as started reading LV2 documentation :)). It will take a
some time to release it because of some other things I have to do in
next few days. BTW it saves the settings on quitting (at least for the
last closed instance) :D
About gain and automatic connecting to ins/outs... Both are actually
leftovers from debugging. It was simpler for me to just run it and not
to mess up with wiring too. Gain is not in dB. It is actual
amplification.
