Audible Mineral Vibration Spectroscopy

RRUFF Raman Data: 2,840 Excellent Unoriented Processed 2019-02

Here, the vibrational Raman spectra of many minerals have been made audible.
The python program that created these sound files is available in the section
title "Current Version". It peak-detects the RRUFF database files and then
does an inverse Fourier transform on the n largest peaks to produce a chord
where the frequencies of the chord's notes are taken from the wavenumbers.
This seemed physically acceptable; but I suspect musically speaking, the 
frequency of the notes should probably be based on a log scale or something 
like that.

In any case, you might expect to hear only a single note for a pure element 
like diamond, but you probably wouldn't expect to hear the same sound for 
an allotrope like graphite.

The RRUFF database of such spectra is available online.
