Look up "mixing" or audio mixers. I have heard audio recordings that have
taken the
"noise" generated by and recored from radio astronomy and mixed with an
audio tone to
give a more pleasant sound. Quite interesting "music" from the stars.

Mmm ?

FYI I found that in Audacity,
http://www.astrosurf.com/lombry/qsl-...e.htm#Audacity
it is possible to export FFT in TXT file (in View, Plot Spectrum, Export).
Then in menu Project, it permits to Import Raw Data... too (in txt, etc).
That works.

The other solution is to find on the Internet something audio processing
"FFT inverse" (FFTI).
But I haven't find a good product yet.

Hi,

Do you know a software that 'd convert a spectrum to voice (the opposite

what do a spectrum analyzer like Audio Wizard or Audacity) ?

The idea is to convert the visual spectrum of stars to voice (e.g. 400nm
to
400Hz.) or a radioastronomical signal recorded at SHF, etc.

I know that acoustic engineers could generate such audio files and some
musicians do such performances, but that means a lot of hardware, what I
cannot offer.

Even if this is a nonsense, maybe that a genious programmer developed
such
tool for mateurs...

Any idea ?

Thanks in advance
