Ceres3 will load L, R, or L+R stereo files.

Its thread safety is probably not so good.

I think your version is the one to keep up-to-date. Libsndfile support
is important, as is JACK support. I can start sending you comments
regarding the major differences between Ceres and Ceres3 if you like.

I had many email exchanges with Dr Hammer during that period. The other
versions had his blessings, he was I think too busy to add things like
WAV file support and stereo file support, and many bugs were not being
addressed. IIRC he was doing more work in paleontology. We occasionally
discussed dinosaurs too... :)

I can see that integrating the codebases would be problematic, but it
might still be helpful to see what actually remains in Ceres3 that has
not yet made it into your code. I'll try to do a more serious comparison
this week and will send the results to you if you want them.

Btw, thank you for all your excellent work in Linux audio software. I
don't know if many people realize how much you've contributed, but I do,
so thank you very much. :)

Best regards,
