Bill,
I have never used your SDL version because it didn't have sound implemented, so my reply may not be relevant. With DOS fractint I never really understood the orbit delay and how it related to the timing, other than to adjust until I was satisfied. It would be a huge bother if the DOS functionality was changed, so I'd say for SDL version just change the docs. Am I correct in my thinking that the SDL version will still not be able to use the sound card other than for emulating the PC speaker? Or do you intend to mirror the DOS fractint implementation?
Considering how long it has taken me to emulate the PC speaker (over a year), I am not inclined to try emulating the more advanced features of a real sound card. There are certainly some features that could be fairly simple to implement.
I now use DOSBox-X version 0.83.7 for all my fractal sound projects. It emulates the DOS fractInt sound function very, very well. When I looked just now for the version in the Help->About DOSBox-X, I noticed for the first time that directly after the version, in parenthesis is "(SDL1, 64-bit). Is there a link between that and your SDL version?
Yes. I am using SDL2 at this point. I've tried looking through the DOSBox source to see how they have implemented sound, but with no success. Jonathan
