"WebDec 27, 2024 · It may take a little more work, but you could change the forward FFT so that it takes its input directly from the real-valued input vector. This is probably close to twice as fast as the complex FFT you are currently doing (but this is just for the forward FFT, so your overall speed increase might be up to 25%). " - Hilbert filter c++
