The bfly functions do multiple loads and stores of Fout e.g. C_ADDTO(*Fout,scratch[3]); Code size and performance is improved by loading Fout at the top of the loop and storing it...

kissfft on ARMv7 with fixed point is slow. A neon version would improve performance quite a bit. 1. there arent enough registers, so the stack is used 2. shifts and...
Hi there, I tweaked the conan recipe for kissfft, it had been missing the extra #defines that the library users needed to include in the compile stage. I was wondering...
(1) Accuracy has been improved in the set up of the _twiddles array. Now sin and cos are only evaluated for angles in [-pi/4, pi/4] and all the elementary symmetries...
Hi Mark I have fiddling with many DSP platforms where KISSFFT does a good job - THANX A MIL. But I have now seen some platforms with a quite string...
I was wondering if you would accept a pull request to add Arduino Support which contains the following changes - new file library.properties in the root directory. - new file...
Currently the code allows for arbitrary numbers of samples in the input. This is great when you need it, but it requires a lot of code that remains unused when...
Should the BSD license instead of and show the actual year and owner of the license?
Right now the install step on windows copies files to the root of your file system. CMAKE_INSTALL_PREFIX is ignored for all files but the lib. That is because CMAKE_INSTALL_* variables...
