Here is a CSD that takes in a stereo soundfile and redistributes its
bins among 6 loudspeakers using the amplitude of the bins for the
gating (with user-defined smoothing). Sounds very strange as you can
imagine!

Hi Peiman,

Why only 6? :)

What are your experiences with different material? Does it really
break the image up, or is the sound image still formed somewhere?

Cheers,
Andrés

Hi Andres,

With much trial and error I've settled on 6 channels. In a concert
situation the rear will be doubled with the sides to cover the gap but
I find that side speakers are really only good for covering the gap
between the front and the back and are not so useful compositionaly.
Having them there I just can't resist the temptation of using them but
when transferred to a larger room the image falls apart as the sound
goes through the side speakers (i.e. the speaker suddenly stands out
if you're sitting to one side). If I had a larger studio I would
certainly work with 8 but then instead of having the extra pair on the
sides I'd put them further away in front to be able to play with
perspective a bit more (this can still be done in live diffusion with
a 6 channel piece). As it stand I have a stereo pair in front and a
sort of quadrophonic set-up around the listener, with the rear being
about 110 degrees (as in 5.1). This gives me most of what I need in a
multichannel context. 8 is overkill I think (I do actually have 8
speakers but two of them are sitting dormant!).

With this csd because I'm treating each side of the speaker array as
an individual channel (perhaps with some leaking sometimes) the image
remains more or less coherent to my ears. Particularly if you use it
less drastically by having only 80-90% wetness. I'd be interested to
hear any comments.

Cheers,
Peiman

Hi Peiman,

Very interesting, thanks for your thoughts. I also find that speakers
exactly on the side are uncomfortable to listen to, even in a large
room like the Sonic lab, when they are more prominent than the rest.
If they are part of a larger "soundscape", they do work well, and I
think filling that gap on the side is useful, although, as is done
traditionally with sound diffusion, putting the same sound in both
frontal and rear speakers will spread the image in interesting and
unexpected ways on the sides. However people too close to the front or
the back will no exerience this (artificial decorrelation will work
wonders here).

Cheers,
Andrés

Thanks Andres, very interesting. So instead of plane amplitude panning
adding a bit of phase/spectral decorrelation to the sides? I'll
experiment with it.

I have to say that most of my multichannel stuff so far works pretty
much only with spectral decorrelation rather than amplitude panning.
Certainly I'm not doing any panning motion other than what's already
in the stereo image (well there is a bit of grain-by-grain panning but
its all statistically distributed or following a pattern of some sort
with high grain density so it's not really perceived as motion as
such).

Best,

Peiman

Hi Peiman,

You could take advantage of the internal dynamic characteristics of a
signal when diffusing (that's why Smalley sounds so good in
multichannel diffusion), or if you're feeling adventurous, you can try
my implementation of artificial decorrelation:
http://www.csounds.com/journal/issue14/PseudoStereo.html

The last one there will allow you to clone a mono signal into two
decorrelated ones, and if you place one in the front and one in the
back, you will see that things will tend to break up more easily on
the sides (and more consistently for more members of the audience).
You can still do stereo pieces, by placing decorrelated copies of left
and right to the corresponding back speakers.

The main issue with this type of decorrelation is that it can
introduce unwanted artifacts. You can keep trying until a particular
random seed works well with your material and then keep that render.

If you gice it a try, let me know how it goes.

Cheers,
Andrés

Do you mean small fader movements following the dynamic shape of the
sound? I've been doing this for a few years in diffusion following
Smalley's advice. With stereo pieces he also delays the rear speakers
by 20-40ms as well as reversing their stereo image, which works very
well too.

I just had a read through. This is great. How would you treat the side
speakers in this case?

Thanks
