LADSPA.jl remarks, improvements?

[fps]

For another project I needed a way to run LADPA plugins to do some audio processing:

GitHub - fps/LADSPA.jl: Julia code to instantiate and run LADSPA plugins

It works allright for my usecase. I never used the FFI in Julia before so I am interested in remarks/comments to make it more canonic/avoid pitfalls, etc.

Thanks!
