Hi, Quick music tech question:

I know how to use a spectral analyser, but how do I do the
opposite, IE generate an image from sound, which will show
up in a spectral analysis program? I have used beep map to
generate sounds, but it's not like they show up like the
source imagine when you spectrally analyse them. Anyone got
any software for this, ideally VST, that they can
recommend?

Thanks.

Coagula Light is a program that will let you either draw a
free-form picture and convert that to a sound, or will let
you import a bitmap of your choosing and create a picture
from that.

if this is what you're talking about anyways :)

fruity loops. serious - there is this "beebmap" plugin which
worked quite fine for me after some tweaking

Coagula does it, yeah. It always gives a really distinctive
sound though, you can tell its an encoded image when you
hear it.
if you open non-audio files in Audacity (import raw data)
and play with the format settings, you can make some lush
electric sounds.

use coagula for computer generated sound...

or use log graph paper and draw by hand. then convert
frequency on y axis to musical notes(quite easy), then play
on any instrument (will prob need some tape splicing
trickery).

That won't sound like any coagula :D

N.B. the timbre of the instrument will cock it up to some
extent due to harmonics, so perhaps use a chruch organ or
something with a sinewave characteristic (i.e. no
harmonics), more complex timbres may lessen the effect. I
have not experimented enough with this because I'm lazy.

i think hes talking about sound to jpeg rather then jpeg to
sound which is what we're used to. i might be wrong though.

im sure it could be done what im talking aboot though.

I'd rather use Coagula.

BTW, if it's the opposite of synthesizing sound, then use
Spectrogram (or Spectrograph if that doesn't google
anything). I think you can export pics with it, but if not,
just Print Screen and edit in Paint.
