GOS imp and Samplitude

[Jeannot Welter]

Hi,

Has anybody been able to use the GOS imp. files in Samplitude 6.0 ?

Thank you.

Hi Jeannnot,

I have been using the GOS Impulses in Samplitude.
Please call or email and I\'ll give you particulars.

Have you seen Samplitude 7.0? Their Room Simulator is going to be able to provide Impulse Response technology in real time. Rumor has it that the room simulator will be able to run multiple instances on a fast machine. It seems that PC users may finally have something like Altiverb.

See: http://www.samplitude.com/de/v7_feat12.htm (\"http://www.samplitude.com/de/v7_feat12.htm\")
for details.

I can run multiple instances of Acoustic mirror on my 1 gig athlon. I figure a 2 gig would scream along fine

Its DX so its not EXACTLY real time since there is some latency...but it works for mixing purposes.

Hi,

Has anybody actually compared convolutions done in Soundforge and in Samplitude using the same GOS impulse file?
Sorry if this becomes OT. I am trying to decide between either software or a TCpowercore.

Any advice is greatly appreciated.

nope, but I wish someone would images/icons/smile.gif

Hi,

I just installed the demo of samplitude 7.0, the GOS .imp files work just fine.

Regards.

I have Samplitude 7 and the Powercore. They\'re an unbeatable combination.

[Jeannot Welter]

Hi Peter,

How do the GOS impulses processed through the room simulator compare to the reverbs the Powercore offers?

Thank you.
Jeannot

I haven\'t tried it as we just finished beta testing Sam7.

Jeannot,

I\'ve been in touch with the Samplitude guys and thought I would inquire directly. This is their reponse:

\"A simple way of using room response files is by loading the response files directly into Samplitude as wave files and then specifying the option \'Loaded Projects\' in the preset settings of the room Simulator. \"

\"Instructions for Samplitude version 7:
There are several ways of setting up a room Simulator sample in Samplitude. If you find that you constantly work with a particular room response, you can save a wave file into a preset folder located in the FX-preset folder in Samplitude. When working with the room Simulator, it will show up in the preset list. Files with the extension RAP can also be saved into that same folder. These types of files are RAM project files, which are loaded entirely into your computers RAM memory. This is especially useful when working with small room response files. RAP files can be created with the convert option in the file menu.\"

Hope this helps.

<font size=\"2\" face=\"Verdana, Arial\">Grandmothers and eggs notwithstanding -this isn\'t right. After importing the impulse response .wav it can only be loaded from the impulse response menu, not in the preset settings. So: import, save in the Fx folder, Load under Impulse Responce, set parameters and go. ...at least in Samp 5 and 6, -I don\'t have 7.

Hi,

After starting this thread some time ago, I have been experimenting with GOS .imp files in the demo versions of Soundforge 6.0 and Samplitude 7.0. The results: Samplitude gives me consistently a denser and richer sound and at the same time is more transparent.
Now, if somebody would just compare Sam with Altiverb...
Keep in mind that this is based on my DAW and my audio system using very transparent speakers.

Best regards.

Hi all,

I\'ve tried out the Samplitude 7 demo, only to get very disappointing result. I did an A/B test with the M-5000 and there was no comparison. S7\'s room simulator simply sounded dead and plastic.

Yet I\'ve been seeing good feedback for the S7 room simulator, which really confused me.

Can someone please share with us your experience of any A/B test of S7\'s room simulator v.s. anything else? Thanks in advance.

[Jeannot Welter]

Hi,

My first results were disappointing. But after a lot of tweaking I am getting exactly what I want. The only .imp file that gives me these results is GOS hall 2. You need to use High (Full Sample Rate) under Advanced. Try a predelay of 18 ms, dry -3db, wet -12db, low 80%, high 60%, you might also want to do minor edits to the .wav.
Hope this helps.

JW.

Jeannot,

I wonder if you have used any of the additional impulses available from the Samplitude website. If so, may I know which ones you rate? I agree tweaking is necessary to get the desired results.

GOS 1 is odd. There is very little HF loss on the reflections, despite the large sounding space. (I’m afraid to bring this up, because I don’t really know what I’m talking about). I wonder whether the impulse wave was EQ’d, perhaps in order to make the instruments sound closer in the mix. I prefer to use this impulse to emulate smaller hall reverb (in fact I have time-contracted the impulse, with further tweaks in the convolver)

Martin,

I did not know that they were available. I\'ll go get them and report in a few days.
Thanks for the info.

Jeannot, I don\'t think they\'re there anymore. There were 90 impulses, with loads of halls, smaller rooms, churches, cathedrals. They came in 3 Zip files of 10MB each. Do you want me to mail them to you?

[Beckers]

You know, -I’ve been thinking: maybe I’ve been doing it all wrong all this time. I’ve spent loads of time tweaking in Room Simulator, trying to get it to sound “right”, just like you would with any reverb. If it sounded stark, metallic or artificial I thought I hadn’t tweaked it right and spent even more time.

But: the impulse contains the characteristics of a particular room at a particular distance from the reflectors. If I want it to sound like a different room I can get closer to it by changing parameters, but this immediately introduces artifact. E.g. using EQ to help make the reflections sound closer/ further, or to emulate different surfaces, affects the sound equally over time; but the change required is likely to be dynamic. Trying to marry up changes in the limited set of parameters available (early and late reflections, time and decay etc), correctly so that it sounds natural, may be too tall an order. And there are other influences on the reflections which you can’t change with these tools.

So, perhaps the answer is: if it needs tweaking you haven’t got the right impulse. I’ve had a look back over the last few years. The most pleasing results have required the least tweaks. After all, there is only one setting which allows the impulse to accurately reproduce the room character at point is was taken. This includes the volume of the wet track: frequently I find that artificial boxyness or is removed just by reducing volume of the wet track. So if I want “more” reverb I need a different, untweaked impulse (with stronger reflections).

Maybe there is no such thing as a good impulse or a bad one, only the right one or the wrong one for your needs.

Martin,

I would really appreciate if you would send the impulses to me: jwelter@attbi.com.
As I said, the best one I have found so far is GOS2. I work in the following way: I try to get the instrument placement as close as possible in the dry mix using eq and vol and especially the keyswitch/velocities instruments in the Dan Dean woodwinds/brass. With these instruments you can make a trumpet player use ff articulations and still make him/her sound far away by lowering the volume and applying eq.
After i have done all I can in the dry mix, applying impulses is much easier and more of an enhancement than a torture to get it right using only impulses or reverb.

Thank you and best regards.
Jeannot.

[Beckers]

OK.

There\'s too many to evaluate properly and I have tended to use the \"Small Wood Room\", which is great for string quartets, and the \"Ambient Hall\", (which is smaller than the GOS ones).

Jeannot,

The email with the Zip attachments was returned to me with an error message saying that the message size exceeds the fixed maximum of 10MB. I tried individual Zip, but same result. I haven\'t got 30MB of band width left to post it, so the only thing left is for me to send you a CDR, or you could ask Samplitude. If you wish you could leave your address in a private message. I\'m sure the copyright owners will not mind me sharing this with a registered Samplitude user.

Do you add the convolved impulses to each instrument individually, with parameters set for their relative positions, or do you add a single impulse to a dry mix? I tend to do the latter as I work mainly with smaller ensembles. Otherwise I do pretty much what you do, but often feel the need for further EQ after adding the wet track.

Martin
