Hi,

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

It already exists, and is called an inverse FFT.

You might also look up _Music from the Galaxies_
by Dr. Fiorella Terenzi, who used radio astronomy
data to make music. The results were interesting...
