Analysis of raw 64bit data at very high samplerates

Hello.

I would need to inspect a signal both in the time and frequency domain and
I was wondering if I could use Audacity for that.

Currently, I'm generating a file with 64bit values in Lua. I was wondering
what kind of formatting does Audacity expect for raw audio: should values
be separated by a space or by a newline?

The samplerates I'm working with are in the order of MHz, would Audacity be
able to support any SR for FFT analysis?

I've tried importing a file where the values are separated by a space as a
raw file using the "64bit float" option and I also tried all possible
endianness options, but I get a noisy signal which has nothing to do with
the sine I'm testing it with.

Thank you so much for your help.

Dario
