Real valued split radix FFT with inverse.
Install: npm install corbanbrook-js
Example usage for corbanbrook-js can be found in the test directory.
This is a partial fork of dsp.js by @corbanbrook which is no longer maintained. It's partial in the sense that I've only taken the real valued FFT. I've also put together a benchmark against other popular Javascript algorithms here.
Thanks to Chris Cannam for the original benchmark tool.
Special mention to @Spudd86 for his pull request which contained the working inverse tranform which is also included here.
Special mention also to Henrik Sorensen who I suspect is two transpiles behind this code in FORTRAN.
The original dsp.js is here.
