I believe all of the audio processing addon libs, (SRC236/SRC441) are built without hardware FPU support. The problem is my entire project was built with hard FPU support. I tried the mixed SW/HW, but that didn't solve the issue and I couldn't build the project. Any ideas?

I removed the sample rate conversion libraries because I do not need them now, but looks like even decoders/encoders themselves are also built without HW FPU support.

You don't have to believe.
UM1640, 4 System requirements and hardware setup:
SRC441 libraries are built to run either on a Cortex® M4 or on a Cortex® M7 core, without FPU usage.
UM1641, 4 System requirements and hardware setup:
SRC236 libraries are built to run either on a Cortex M4 or on a Cortex M7 core, without FPU usage.

That's absolutely true! I just wanted to say, "I believe" there's no other alternative. Some libs are available in different version (w/out) HW FPU. So, what would be the best solution in this case? I can't drop HW FPU on this particular project, but still need to incorporate some of the audio expansion package. Probably switch to another solution?
