Re: [Discuss-gnuradio] FFT algorithm used in FFT block

So according to the link the library doesn't utilize one particular algorithm but is optimized to use the "best" algorithm depending on n according to this link

https://cnx.org/contents/ulXtQbN7@15/Implementing-FFTs-in-Practice

So, is there any particular way to figure out which algorithm is used when using the block in a flow graph?

Scroll down to the "Literature" section for detailed papers.
