Developers looking for mobile-specific implementations can find a compact version with Android JNI wrappers at berndporr/kiss-fft . 2. Key Features and Performance kiss_fft download

The core routines are thread-safe and do not rely on static memory. 3. Quick Start Guide: Installation and Usage #include "kiss_fft

Efficiently handles FFT sizes that are not powers of two by using factors of 2, 3, 4, and 5. Execute transform kiss_fft(cfg, cx_in, cx_out); // 4

KISS FFT's design philosophy prioritizes simplicity and portability over achieving the "fastest transform in the world".

One of the main draws of KISS FFT is that you often don't need to "install" it in the traditional sense; you can simply include the source files in your project. Simple Compilation
