Re: [Audacity-devel] VST interface

[Dominic M. <do...@au...>]

George,

This is an annoying situation.

We can't use VST directly in Audacity because the VST header files  
are not open-source compatible.  :(  So unfortunately the only  
solution we have is to support the LADSPA interface in Audacity  
(which does not include support for labels!) and then implement the  
VST Enabler, which is a LADSPA plug-in.

Steve Harris, are you listening?  Will LADSPA 2.0 include the ability  
to create labels???

One solution is that we could create an Audacity plug-in interface  
that has all of the features we want.  I'm not sure I want to create  
yet another API that looks the same as all of the others...  What  
about a socket-based interface?  Has anyone written an audio  
processing "plug-in" system that is based on a bunch of programs  
sending packets around?  :)  One thing I like about that is that it's  
language-neutral.  I'm still big on writing plug-ins in Python!

George, as for you, I'm afraid that right now your only solution is  
going to be to add your functionality directly to Audacity.  We'd  
also love your help improving Audacity's plug-in interface but that  
will certainly take more time.

Can you tell us more about what your plug-in does?
