VectorFFT is a vectorized, pure C FFT library optimized for x86 processors (AVX-512, AVX2, SSE2) with zero external dependencies. It implements mixed-radix algorithms for common sizes and Bluestein's method for arbitrary lengths, with OpenMP multi-threading for large transforms. Designed for both digital signal processing and financial applications
