The fastest FFT and polar-FFT

Android FFT,stft,polar,rectangular,pi,tau manifestoCan be used in native apps on Android, iOS, macOS, tvOS, Linux and Windows, and in all major web browsers: Chrome, Firefox, Safari, Edge, Opera, etc.

FFT is used everywhere. Image, video, audio and biomedical signal processing, just to name a few. FFT is a very CPU-intensive transformation and everybody wants the fastest solution. It’s here.

Until Superpowered, Apple’s vDSP had the fastest FFT for mobile devices. There are some other libraries claiming they have a faster solution, but every time we download and test those, they always fail to deliver on the devices we have.

The Superpowered FFT processes with the same speed as Apple’s vDSP. We don’t claim we’re faster (sometimes we do), but definitely not slower.

Polar FFT

FFT by itself is not really useful when you need to work with magnitudes and phases (such as audio), not just complex numbers. In this case, you need Polar FFT.

We made it super convenient for you: just one call to do the whole transformation. And here is the big deal: the Superpowered Polar FFT is at least 2x faster than Apple’s vDSP.
