Hi,

first: I don't know the sox source code, so I have no Idea, what
sox/soxr really does, but:

Why don't you give it a different amount of frames, like 4800? So you
would get 4410 frames back and everything is fine.

greetings,
Erich

I realize this list is for neither of those libraries, but afaik soxr is extracted from SoX just with a different API, and I think my issue is in dealing with the resulting data, and not the API.

What is the proper way to handle the 0.2 frames in this case? Does the library handle that transparently? Or should I be doing some amount of math to figure out leap-frames every few cycles? No examples I’ve seen explicitly handle this, so I’m guessing it’s unnecessary, but I’m running out of other avenues to try to fix the problem I’m having, so I’ve kind of gone back to basics.
