I've been aware of Dirac for some time. Its not feasible to use his

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.
Given that Rubberband was really the first
library available on Linux
without a license that could do high quality timestretching, its not
really suprising that there are not that many apps which support this
(*).
Rubberband is interesting, but when I had to develop a professional tool to time
stretch voice recordings, the quality was far from acceptable.
In the end, I used Dirac. The quality's amazing. It's not open source, but
there's a free version with a rather permissive license (44.1/48Khz only).
Also, the author has recently added Linux object libs.

What about adding (optional) support for it in Ardour, as an alternative to
Rubberband?
