The Faster-than-Fast Fourier Transform

Improving The Fast Fourier Transform

The Faster-than-Fast Fourier Transform can replace the Fast Fourier Transform to save processing time when digitising an analogue signal.

For a large range of practically useful cases, MIT researchers find a way to increase the speed of one of the most important algorithms in the information sciences. – Larry Hardesty, MIT News Office.

Well this might be the case but it could so easily be that everyone takes it at face value and embodies this algorithm into all new electronic sound and video processors. We may then find all our music and video content degraded as a consequence. Then it will be too late. With the Faster-than-Fast Fourier Transform processing sound and video is quicker and cheaper so we’ll be stuck with it. Musicians who prefer analogue sound reproduction may find this degrades digital sound further. On the other hand it could improve the quality.
