FFT, internal precision #6

Closed abique closed 7 years ago

abique commented 7 years ago

Hi,

I wonder if it is possible to feed the FFT with a float input and output but use double internally for all the computation?

Or is it just faster/easier to use convert the buffers to doubles first then call the fft?

Thank you very much!

Hi,

It is perfectly possible to make a wrapper class that will convert the data and perform the computations in double precision.
