SoX is a sound tool. You can force it to turn into sound any
series of bits. Most of us would probably call any such file
"noise", not "sound".
SoX can be used to generate spectrum like images from sound...

Err. I don't understand how sound can have a 3D surface.

No. MIDI is NOT a sound file, it is a set of playing instructions
- like an old-fashioned player piano.
