Re: [music-dsp] Faster Fourier transform from 2012?

A guy on the linkedin DSP group posted about "System Compression" as well, which is related to compressive sensing. I haven't looked into it at all, but here's the link: https://www.linkedin.com/groups/144812/144812-6155834561751191554 In case you can't access that link, he doesn't give much

Not sure what you mean by this being 'real', but indeed there are faster algorithms than the FFT if the signal is 'sparse' (or approximately sparse) in the Fourier domain. This is essentially the same idea as in compressed sensing, where you can 'beat' the Nyquist criterion for sparse signals.

[music-dsp] Faster Fourier transform from 2012?

This article has been getting shared and reshared by some graphics professionals / researchers I know on twitter. The article itself and arxiv paper are from 2012 though, which makes me wonder why we haven't heard more about this? Does anyone know if this is real?
