He’s using a Fast Fourier Transform routine crafted in C to run as efficiently as possible on the 8-bit chip. The video after the break shows that the results are quite pleasing, with just a bit ...

Say you strike a chord on a piano ... Vorbis uses a fast-as-lightning computational version of the Fourier transform called a discrete cosine transform, but it’s broadly speaking the same ...

These are known as Fast Fourier Transforms (FFTs). [klafyvel] set upon diving deep into the mathematics involved, as well as some low-level programming techniques to figure out if the trade-offs ...

improves on the fast Fourier transform. At the Association for Computing Machinery's Symposium on Discrete Algorithms (SODA), a group of MIT researchers will present a new algorithm that ...

When you listen to digital music, the harmonies and chords ... are the Fourier transform of the crystal’s structure. Modern incarnations of Fourier analysis include the ‘fast Fourier transform ...
