… data, not real game. Also did not compile the original project, only a bogus project.

Cleaned this up a fair bit and plugged it into a new system that includes scalar fallbacks:

8thMage#1

The resampler code needs cleaning up but it sounds okay to me!

With the above changes I did manage to get a crash, but the good news is it's consistent. If you own Dust: AET, the Content/sfx/ folder should have sfx_project.xgs and weather_wavs.xwb. You can make facttool, load those two files (ignore the streaming assert), and playing wave 0 should crash after about half a second. (If you don't have these files, e-mail me and I'll send it over.)

Using an isolated test program with the exact same raw MSADPCM data works fine, so I think this is just an alignment issue.

i changed the mono SSE2 functions from using doubles to using floats. The double function was not checked like the float function, so it makes sense it crashed. the float function now has better variable names and explanation for most of the non trivial work.

[flibitijibibo]

That fixed it! I'll run through this one more time with some of my stuff, do one last cleanup (your editor really hates /**/ comments!), and we'll get this merged in.

This should be the last of it: 8thMage#2
