Inverse chirp z-transform (ICZT)

Have the FabFilter geniuses seen the new research on the inverse chirp-z transform (think inverse FFT)? This could be significant advance in DSP technology and I'm curious when this will show up in the next versions of FF software (:-).

Researchers have found an O(N log N) solution which is a significant advance over previous versions. See this article for an overview: techxplore.com/news/2019-10-year-old-puzzle.html

The research is described in more detail here: www.nature.com/articles/s41598-019-50234-9
