Please, it would be great to add a description of it on http://plugin.org.uk/ladspa-swh/docs/ladspa-swh.html (keeping consistency up to date).

@swh can you please add the vocoder instructions to your HTML?

Hmm... The LMMS instructions are too wordy and too specific to LMMS.

Here's my version. Feel free to modify...

Vocoder or "Voice Encoder" can create a pitched voice based on a second input signal.

  • To use this plugin, pass two tracks through it at once
    • Pan the voice to the full left
    • Pan the carrier wave to the full right

The output is a vocoded voice track based on the carrier wave. Hint: Use saw wave, NOT sign wave as right channel must contain contain a broad wave-spectrum, with several overtones.

The docs are generated automatically from the XML source, see https://github.com/swh/ladspa/blob/master/docs/Makefile

Unfortunately I don't have a current build system that can run them, my hosting account used to have all the needed tools built, but it's so long since I ran it that the binaries won't execute anymore.

I'll have a go at getting a docs build environment working at some point, but it's likely to be a couple of months - I'm out of the country for most of June. It needs some pretty ancient software.

@trebmuh, @tresf, I am not sure this is an issue. http://plugin.org.uk/ladspa-swh/docs/ladspa-swh.html is consistent because http://plugin.org.uk/ladspa-swh/ does not have vocoder. The documentation is autogenerated from the XML files. In GitHub, vocoder already has a basic description:

Makes a human voice sound synthetic; often used to speak like a robot, with a metallic and monotonous voice. Using a human voice as the formant and an instrument as the carrier, creates an effect of an instrument speaking.

Panning to left and right channels is specific to LMMS; the plug-in has Formant-in and Carrier-in inputs. Perhaps the hint about "use saw wave, not sine wave" could be added.

@jasp00 good points. Can do the documentation PR?

@tresf, done in #31.

Awesome. Thanks to you all.
