News

2010/02/18, I've decided to abandon development of standalone version and maintain only LV2 version of VocProc, starting from verion 0.2

2010/02/03, Jeremy http://linux.autostatic.com has made little soundclip using (among other things) VocProc. It can be found here

2010/02/03, Ubuntu Karmic packages available at https://launchpad.net/~philip5/+archive/extra/+sourcepub/950775/+listing-archive-extra. Info about adding this repository can be found here (thanks to Jeremy and Philip).

Download

VocProc source can be downloaded from:

Standalone version (not maintained anymore): http://f.hyperglitch.com/vocproc/VocProc-0.12.2.tar.gz

Building and requirements

To build it you need to have installed gtkmm-2.4, lv2-c++-tools and fftw3. These packages are also available in most distro's repositories (note to Debian/Ubuntu users: you need to get dev packages. AFAIK lv2-c++-tools is not in standard repositories so you'll have to compile it yourself. It requires libboost-dev for building).

README file.

Building process:

(edit the Makefile if needed)
> make
> make install

Uninstalation:

> make uninstall

Note: It is possible to build VocProc with or without vocoder functionality. This is described in README and Makefile files.

TODO

  • reduce the oscilation between tones on tone transitions
  • improvement (optimization) of pitch detecting algorithm
  • MIDI control (maybe)
  • various optimizations
  • ...

BUGS

  • first release as a LV2 plugin so we'll see...
