[Scilab-users] ?==?utf-8?q? Accessing sound device using java api from scilab

[Antoine Monmayrant]

Hello Samuel,

I'll be really happy if you can keep me up to date with the evolution of this project.
If you want someone to beta-test the macros or there documentation, I'll be happy to assist.

Cheers,

Antoine
