Profiling report
I tested a few samples while profiling and this is what I get on a few samples.

Not surprising the transform takes most of the time and frame parsing is next.

If we already sharing... On my XLL sample it spends more time there.

EDIT: GCC 4.9.2, mingw-w64 3.3.0. dcadec compiled with unmodified settings apart from -pg ofc. EDIT2: But to be honest I see no point in this issue. I'm sure foo89 can use profiler on his own.

Aren't compiler vendor and settings extremely important here? The project is 100% C code. So maybe you should post compiler version and optimization settings too.
Also interesting to finally see a case where the restrict keyword actually does something.
