Space Designer True Stereo Impulse Responses

I recently purchased some impulse responses. I am trying to load these into Space Designer on Logic 9.1. They have been supplied as L, R and C wav files. It says that Space Designer supports 'true stereo' impulse responses, where there is a seperate wav file for L and R. But I can't work out how to load both files? Has anyone on here successfully loaded True Stereo responses in Space Designer? The set of responses also includes 'quad' files consisting of just one stereo file - should I be using these instead?
If anyone could help/offer any advice I would be very grateful
Many thanks

If the impulse responses are Stereo Interleaved audio files, then they load into Space Designer as true stereo impulses.
Note : make SURE you create the space Designer on a STEREO AUX or channel, otherwise its mono--->Stereo, and will load mono impulses. At least that what it does on my system. They same impulse sounds very different when fed a mono source VS a stereo source...
As for "QUAD" sources, it does not support them, at least I do not think it does.
Try loading a Space Designer on a 4-channel audio track (a QUAD) track, and see what happens.
Also, those QUAD files are probably 4 mono audio files contained in the one file. I've seen these before...

Can Space Designer import true stereo impulse responses?

SD can import a stereo impulse response, which basically functions as mono input to stereo output.
In order to do true stereo (stereo in, stereo out) requires two stereo impulse responses. Some verbs import two stereo files, others import quad files.
The manual says that SD uses true stereo, but there isn't any more information about it. It looks like there are a few true stereo presets, which have a + after the preset name and display "Discrete Circle" in the window instead of stereo, but I can't figure out what file format they are or how many channels (they are SDIR files, but looks like those can't be opened).
SD does allow importing quad files, but they show up as "no mode set" and don't sound like they're working right.
Anyone have any experience with this, I'd like to be able to use some true stereo IR's but at this point it looks like I may just have to buy another reverb plug if I can't get that working. Thanks.

it looks like that can only work with files it records itself, I don't see an option to import files.
I tried to find a way around that and I came to the same conclusion as you.
in all cases the verb was all in the right channel even though all four channels of the file had signal
I think I found a way to get results better than that, but the results still aren't really right. I've been using this file:
L96, 01-02 Medium Hall Quad.wav
It's the same one I mentioned in the other thread. I load SD, and then I drag this file in. I don't change any SD settings before or after I drag in the file. The source material is various stereo Apple Loops, and some other test files. I have SD on an Aux, so I can easily solo the Aux and hear 100% wet signal.
The wet signal is on both sides, if there is a source signal on both sides. When the source is panned hard left, the wet signal follows, and vice versa. Instruments that start out 100% left stay that way in the wet signal.
This is better than what you got, but it's still not right. It's not what you get with the true stereo presets in SD, where a hard-panned source will produce a wet signal on both sides (but with it mostly dry on the near side and mostly wet on the far side).
they show up as "no mode set"
That's what I see, and this is probably a clue that SD is not going to use it to produce true stereo.
I can get those results consistently, but then it starts to break more dramatically if I load an SD preset (any kind at all, as far as I can tell), and then drag in the quad file. Then all sorts of strange things happen. Sudddenly I get 100% dry signal on one side, even though it should be 100% wet. Then this happens on both sides. And the problem persists when I load another preset (without dragging in the quad file again). At one point I would get a persistent loud pop on one side, followed by silence, every time I hit play.
Once it gets in this state, unloading and reloading SD doesn't fix it, and closing and opening the project doesn't fix it. But if I quit and relaunch Logic, that fixes it (although it's still not true stereo).
So I don't know how to make it really work, but maybe this will help you get closer to a solution.

Space Designer True Stereo file channel config.

X-Post
I'm trying batch convert IR's for Logic users.
I have created true stereo IR's (not with the logic impulse utility)
They are currently 2 interleaved stereo .wav files
Left Side-Left&Right.wav
Right Side-Left&Right.wav
For Space Designer to load true stereo it needs to see a single 4channel interleaved file? Is this correct? If so what is the channel configuration & or naming convention/header or quicktime meteadata to let SD know what to do?

Just to try to help: as you say, this is a cross-post. Perhaps if any Impulse Response Utility users would like to respond, it might be better for them to do so in the +Logic Pro 8 Forum.+ There are a lot more experts in there… you may have had a reply already by now!

Space Designer Presets and Impulses... Gone?!

I'm stymied...
Been wanting to audition some Space Designer reverbs, but for some reason all of the presets were gone from the settings menu. I don't remember what I did exactly, but I found them and moved them into the SD settings folder somewhere on my system. And now I have all of my presets back. But...
Every time I load one of the presets, Logic asks me where the .sdir file is for it.
This never used to be a problem. Why it's different today is beyond me. But anyway...
Can someone please tell me where .sdir files are supposed to be located? And also, just so I'm sure everything is where it should be, where should the SD preset settings live?
-=iS=-

Works perfectly.
For some reason my impulse responses and settings were in two places:
iSchwartz HD/Library/Logic/Impulse Responses
...and...
~/Library/Applications Support/Logic/Impulse Responses
Weird...
Anyway, thanks again.

L8 missing L7's missing Space Designer's stereo delay ???

I just upgraded to Logic 8 from Logic 7, I know I'm a bit behind. But my absolute favorite plug-in in L7 was in Space Designer "long vocals" the stereo delay. It was sooo good. So now I upgraded to L8 and I can't find it in Space Designer. It seems like they took it out! Does anyone know where this effect is in L8? Please help me if you can! My email is [email protected] thank you!

hey, im not sure exactly what you're looking for. but try going to the unofficial logic pro help forums ( http://www.logicprohelp.com/ ). scroll down to plugins and channel strip settings, and im pretty sure there is a thread there for it... oh actually infact, here it is : http://www.logicprohelp.com/viewtopic.php?t=45520
just remember to thank the guys at the forum, as its only polite..

Why are L&R outputs uneven w/ Space Designer?

Hi,
In tweaking my studio setup, I took this approach to balancing my monitors:
I loaded the TestOsc plugin - which gave a balanced L & R output within Logic as expected; I then adjusted the amps of each monitor speaker so as to properly balance them.
Then: I un-bypassed Space Designer on the Master output (with the TestOsc running) and discovered that it (Space Des..) is strongly affecting the stereo balance - as observable at the Master Out VU meters (& speaker output). The phenomenon is different with various individual SD presets...
Why is this happening?
I'm concerned about creating my mix in a large orchestral template without an understanding & control of this phenomenon....
Thanks, Wm

Because Space Designer uses stereo *impulse response* files, through which the audio is processed into reverb. If you do not dial in any Dry signal (did you?) you will hear only the fully processed signal. This can vary enormously, as it is shaped by the impulse response file, which is effectively an audio file. It determines what happens to processed signal. Now if you only hear the processed signal, the differences between presets can be as big as the differences between any two audio files.
So... you may have to adjust the Dry-Wet dials on the right of the SpaceDesigner interface. to balance the reverb and the original signal.
Socalled Send presets have no dry signal dialed in, because sent signals should be fully processed and not 'double up' the original signal.
O, and on the left of the SD-interface is a slider to alter the stereo image, which can also be set to mono.
I'm concerned about creating my mix in a large orchestral template without an understanding & control of this phenomenon....
O, I also think that a test oscillator is not the best "guinea-rig" to try out a convolution reverb - unless you're seriously engineeringly measuring stuff, just try 'm with their intended instrument...

Impulse Response editing - Do it the right way: IRs for Space Designer

Dear fellow board members,
after doing several research on this topic and many attempts to match some Impulse Responses I finally have to admit, that a little help or insight would be much appreciated. Most of the (Beamsonic) IRs, especially the Studer and Ampeg IRs, seem to have overlength (≈ 6 sec.) and some do have "silence" at the very beginning (see picture below).
I would be thankful for a helping hand explaining me, which part of this IR is of relevant importance: Do I need the "silence" tail at the end? What should I take care of when editing such IRs as the pictured one? Would only the marked yellow area be of importance? Get rid of the red areas (beginning & end)?
As many of the IRs I do have correspond to the image above, I have to go through heavy manual editing and before doing so, your help would be much appreciated.
Does anybody have gone through this before and would like to exchange some of his material for the Space Designer (IRs + corresponding Presets)? I am looking for: EMT 250, Studer A80 Tape, other Tape Sats as well, Ampeg, Westlake Studio D, other useful top quality IRs as well.
For now, many thanks in advance for sharing interest

1. You maybe want to comment on what is considered to be the
"technical right way" to achieve DAW Tape Saturation via IRs, i.e.
what makes sense and what not?
Really, there is no technical right way - all we are doing is altering our recorded audio in a way that we like - it will vary depending on your tools, your tastes, the material, the artistic intent etc...
a - Insert the Convolution Reverb right on the Audio Channel
itself with Pre/Post-Compression/EQing, etc.
I will do this if I want to process an individual channel for colour. Remember to set the effect to 100% wet.
b - Send audio to a Convolution Reverb Bus (and share w/multiple
audio channels), loss of quality, etc?
You're just sending a bunch of channels - in convolution terms, the results as far as I know will be the same if you process 10 channels indivdually and sum them, compared to if you sum the 10 channels then convolute them. Remember, convolution is a static process in most tools, including Space Designer.
How would you judge the value of using "Impulse Responses"
in comparison to "Plug-Ins"?
Well, I don't think anyone's done a tape saturation plugin properly yet. I'm not an expert in this field, but had some interesting discussions with one of the Sonalksis developers over on KVR who is heavily researching into tape saturation (he's doing a doctorate in the subject) and he thinks that it is possible to do a decent tape saturation plugin - not easy by a long stretch, but possible, so I'm sure we will eventually see decent plugs appearing.
Having said that, I'm not actually a huge fan of the tape sound anyway - I like the impulses for that colour if I need it, but I certainly don't run everything through it. I don't really like the smeared transients, at least on my "less natural" pieces. Rock music (as an example) may well work better.
The plugins that do saturation in varying amounts are a mixed bag in my opinion. A lot of people love VintageWarmer, but I'm not that keen on it (again, I'm not an "expert" by a long stretch, these are just my personal opinions).
I've had some great results using Guitar Amp Pro for saturation and warming (we're talking subtle stuff here) on drums and guitars.
There are a bunch of other plugs too, but none that I have used to tape saturation. DUY's tape does saturation, but not really accurate tape simulation *from what I have heard* - I haven't used it personally myself. Charles Dye seems to like it, anyway!
. Finally: Did anybody experiance differences in quality when
comparing Convolution Reverbs (i.e. SD vs Altiverb vs Waves) in
processing the same IR?
In general, no. Mathmatical convolution is afaiu a mathmatically "perfect" process, much like the adding of audio signals in the digital realm. As long as you know how to do the maths correctly, there should be no difference, given the same IR (it's the IR that really determines the quality of the output).
Of course, different plugs implement things differently, and have different features, but by and large, the convolution engines these things use should be generally the same.
Again, I'm no expert and haven't done exhaustive testing or anything - this info comes from discussions I have and my understanding of these processes from a DSP point of view. Other may well be able to back up or debunk what I've said, so I'll leave the floor to them now...

Impulse responses for Space Designer

Hola,
Anyone know of third party companies making high end impulse responses for Space Designer?
I am particularly interested in finding an authentic spring reverb for dub style tracks ala Lee 'Scratch' Perry.
Thanks for any leads.

don't know if you consider them high end or low end but these ones are free

Space Designer How to load impulse responses from meny?

I'm trying to get Logic to regocnize the impulse responses I've put in the /Library/App Support/Logic/Impulse Responses.
I have to load any external impulse manually. Is there a way to get them just in the "Load" meny as the presets are to save time and to make it easy to browse trough?
Double 2.5 GHZ PowerPc G5 Mac OS X (10.3.9)

Alllright... Maybe a suggestion for apple then to fix so that it's like in the EXS24.. Refresh or sumtin ?
In Altiverb I've seen that it's just to put them all in a folder and then the program scans it to be in the presets list.
Anyway, thanks for letting me know.

Space designer stereo spread enigma

can anyone enlighten me as to why the stereo spread control on space designer seems more often than not to be greyed out?

But to get right to it, it only works on synthesized impulse responses, not IR samples, or when used on a mono track (obviously).

Original Sp.Designer Impulse Responses. On Which Disc?

Hello!
When I first installed LP7, I didn't install any Impulse Responses. I guess i must have done a "Custom Install".
Now that I've started using Space Designer though, i need to find these and install them. Which Installation disc are they on?
Logic 'Content Disc' ? Or the normal Logic installation Disc ?
Logic 'Content Disc' requires some 3GB to install and gives the user no option to select which files to install. Since there is no mention if the 'Content' Disc contains any Impulse Responses, i would prefer to avoid such a waste of HD space.
Thanks a lot.

BTW......
The Imulse Reponses from Logic 7 are not that great.......
Go to this site and download the IR's

Impulses loaded into Space Designer?

Hey does anybody know how to load impulse responses into Space Designer? Just downloaded some third party stuff and wanted to try them out. They are called "Beamsonic Impulses". Thanks

Yeah, using gates would be clumsy and buggy. What the Sonic Birth API does is is allow you to construct your own AU by instatiating actual code. But you don't have to really write the code. You drag visual modules around and link them with virtual cables. Each module is ultimately a C++ class function and you're really just building object oriented code with a GUI. There really is very little you can't do. For example, you can even attentuate output amplitudes with whatever function or equation you wish to write. Recently I wrote a fade in/fade out plug that follows exponential curves when a timing loop is started by a boolean variable switching from 0 to 1. Designing a virtual logic circuit to test the input for its amplitude is very easy and that could be used as a trigger to switch between the output of several convolutions. To the end user it would look like any other AU if you packaged the IR wave files with the plug you create and set them up as presets. The catch is that the user has to actually have the Sonic Birth framework on their machine to use it. It doesn't make a generic AU that everyone can use.
If I get this baby working I'm gonna get real excited.

Space Designer impulses *HELP*

I have some extra Space Designer impulses from my 2nd install disk on Logic 6.
They are a heap of .SDIR files arranged in corresponding directories.
I have copied them to: system/library/application support/logic/impulse responses
Is there a way to get them to come up in the preset menu without having to load each .SDIR and save it as a preset??

Chances are, if you recreate the folder structure that Logic 6 used to store your .SDIR files and presets, Logic 7 may pick it up. Otherwise, I would agree with Marty in that you will have your work cut out for you.

Missing some impulse resposes for Space Designer

I just realized that that the impulse respones for the "Warped effects" are missing. They are not located under the Library/Audio/Impulse responses/Apple folder where the others are.
Does anyone know how to get them?
I'm on Logic Pro 9.1.1
Thanks Morten

In the folder you describe, I have 4 folders, Large, Medium, Small, and Surround Spaces. In each of those folders is another folder for "Warped." Do you not have that?
I also found an Impulse Response folder in Library/Application Support/Soundtrack Pro. You could look there or see if there's one in the Logic folder. Nothing that was marked "Warped", but there were some of the same responses in there.

96k Space Designer impulses ?

Since all the factory presets for Space Designer default to "sample rate/2" in a 96k project, I'm assuming the factory impulses are all at 44.1k ?
Any chance there are higher sampling rate versions of these factory impulses hidden somewhere ?
Guessing the answer is "No" ...

I'm pretty sure I remember reading somewhere, maybe the Audio Ease website, that there's really no need to sample reverbs at anything about 48khz, as reverberations rarely contain frequencies over 18khz anyway.
Makes sense. On the other hand, I'm guessing running a 44.1k impulse in a 96k session requires at minimum a realtime sample rate conversion, which will probably degrade the performance of the original impulse.
Not to mention that a 44.1k sample in a 96k session won't necessarily use less CPU... possible that it uses more than a 96k impulse running at the native sample rate. I haven't tried to test.
Probably splitting hairs here, but I'm curious...
