I've been aware of Dirac for some time. Its not feasible to use his license in combination with Ardour without creating a fairly complex plugin APi. Why? His license is a license for the developer, and it won't permit source redistribution. Since Ardour links against at least 1 GPL library, it would violate the GPL to distribute Ardour with Dirac support as a compile+link time option. I'm not against the idea of a plugin API for time FX backends, I've just got better things to do at this point in time, and for the foreseeable future. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
