space designer true stereo

[mattianlaseppia]

hello

any one can explain me why the manual says the space designer is true stereo while it isn't?

thanks

[jamwerks]

It isn't true stereo?

[mattianlaseppia]

yes, you can't load the L - R - C files.. just one file at time

[mattianlaseppia]

ok.. someone can give me an answer?

thanks!

[jamwerks]

I think that I remember reading in the manual that in Logic 8, Space designer became true stereo.

[mattianlaseppia]

i've read the same.. but a true stereo IR reverb isn't one which can load the L - C - R files both stereo files.. i've the halls of fame IR library and it's true stereo and each impulse are three files.

[jamwerks]

There's an informative article that can be found on the TC electrons website that explains the difference between a true stereo reverb and a "not really stereo" reverb. To be true stereo you only need two files. The center is a common part (I think) of the two and can be mathimatically dirived from them.

[mattianlaseppia]

ok, but the space designer can't load even 2 files at time..

[SFTPH]

It can load stereo interleaved files but not split stereo. Throw your split impulses into logic and bounce them as interleaved and you should be good.

[mattianlaseppia]

probably you haven't understood..

TRUE STEREO is 2 STEREO files.. so.. how to bounce 2 stereo files in one?
and why is called TRUE STEREO a reverb that doesn't allow to load 2 stereo files?

maybe i'm mistaken but i think not..

[SFTPH]

You don't need 2 stereo files. Have you ever seen a piece of hardware with more than stereo I/O?

[mattianlaseppia]

so why true stereo IR reverb are the ones which can load 2 stereo impulses? the others are the normal stereo IR reverb..

if not give me the definition

which is a TRUE STEREO IR reverb?

and which is a just STEREO IR reverb?

[SFTPH]

What reverb uses 2 stereo impulses? That plug must be the only true stereo hard/software that exists. You only need as many channels as ears (for stereo)-most people only have 2 of 'em so a single stereo file is good enough.

mattianlaseppia: You are thinking of split stereo files like sd, those are two mono files, (L, R) that when put together becomes stereo. An interleaved file have L and R packed in one file.

[David Robinson]

hi guys,
yep, got the same query.

apparently there ARE some true stereo files in the lot that's bundled in lp8, but there's no clear indication as to which files they are.

i've tried a number of the surround spaces/HD, etc but they increase the load and do weird things to my stereo image.

sometimes, i just make a better, more stereo/wider one using SD's own reverb generator.

we live in hope,

DR9.

the true stereo files are the one with * after them.

the point is that halls of fame has three or more files for each impulse.. an L and R and C other times has also only ER only Tail of the same impulse..

and i've read that those are TRUE STEREO the halls of fame manual says the same..

if you open the impulse response utility of logic 8 you can see that if you choose to record a stereo IR there are 2 channels L and R if you choose to record a true stereo IR there are 2 stereo channels L and R both stereo..

i've tried to use that utility to combine the two stereo L and R and save them as a SDIR.. but seems not possible..

so i don't understand why they call it true stereo.. for just the 4/5 impulses marked with *?

[noiseflaw]

I do not think you can load 'True Stereo' files in Logic Pro 8 - I cannot find the True Stereo presets with * after the name.

Can someone please clarify?...

There are a few True Stereo presets that come with the standard Installation. At least on my system they are marked with a "+"

I can remember building some True Stereo presets from the Hall Of Fame DVD which was kind of complicated because this is not very well documented.
As far as I recall, you had to use quicktime to build quadrophonic audio Files from the two stereo files of each impulse. IR Utility can read them and create a preset for space designer out of that.

oh yes finally an explanation...
the absurd thing is that you cant use the IR utility to build them, or at least i havent found the way yet.

how to build that quadrophonic if you remember?

[DTA]

Huuhh... unfortunately I don´t have the cd with me right now.

As far as I can remember, there´s two stereo Files for each impulse. You have to both open them in quicktime, and copy / paste them together. Ending up with a "movie" which contains 4 Audio Tracks.
Now comes the tricky part – you have to distribute the channels to front / rear left / right in the quicktime properties window. I however can not recall which channel goes where, sorry.
After doing that, you can save it as a Quadrophonic Audio File. This file can be read by the IR Utility which also creates a preset for the space designer.
The Sapce Designer window should promt "discrete circle" when you load the setting an it is recognized as a true stereo impulse....

great!! thanks really!

logic is always more illogic as anyone know and this is another proof...

As it always is in 21st century computing ;-)

Thanks DTA I will check to find them.

I do wish this Covo verb was more flexible though and could load the true stereo files I have bought!

[noiseflaw]

I have found a convo app that can process 96khz 24bit True stereo L + R impulses I have.

LAConvolver

It sounds better than my Altiverb and Space Designer for playback of the same impulses Why?.. because SD will not load 96khz files so i have to convert them, and it sounds meatier and retains the body better. It's a bit fiddly though.

It is also free.

Lernvall Audio

Great plug! Tobias Lernvall - thanks and well done!

I'm also trying to sort things out for true stereo impulses in Space Designer... since this thread is quite a few months old, perhaps someone can shed a new light.

To sum it up.

- I haven't yet found the way to load in SD the two discrete stereo IRs requested to make a true stereo convo reverb. I gathered from the previous posts it takes Quick Time to assemble the 4 channels of IR into a single file, because obviously SD can only load a single (multichannel) impulse. Is it correct? If so, how do you distribute the channels (I'd guess 1/2/3/4 = 1L/1R/2L/2R)?

- I've downloaded LAconvolcer, and I love its "barebone convolution engine" philosophy however handling of the IRs is not very ergonomic (you got to go all the way to your IR folder everytime, for instance). But... I'm not sure it uses both channels of both impulses, I rather suspect it "simplifies" things by summing the left channel of impulse 1 with the right channel of impulse 2. Can anybody confirm this? I sent an email to Tobias, but haven't had an answer so far.

Your help is greatly appreciated. Thanx!
