Haven't tested the sound, but the venues look nice! Pity that the stages without seats are a bit "boring". Maybe you could integrate, for example in the Synchron Stage, a back wall / panelling with lights or side walls with doors, the big video screen etc. ;)

I have some suggestions ...

• 3D venue control / movement with pressed and hold right mouse button instead of pressing another key (CMD on Mac).
• Improved visibility of the grid. On the Synchron Stage, for example, it's impossible to see something.
• Have a right click menu option for the role assignments (like for the instrument profiles).

... and one issue

• I have noticed when I select a preset (which is MIRx with legacy wording, right?), it chooses the right position and custom character EQ, but the room EQ isn't applied.

Should legacy Rooms packs Vienna MIR PRO be deleted? Or should they coexist with the Vienna MIR 3D Rooms packs? Thanks Carlos

Hi Dietz,

I remember suggesting something almost exactly like MIR 3D a few years ago on the Steinberg Nuendo forum... Congratulations, MIR 3D looks simply amazing. Can't wait to plug it into my workspace.

All the best, António

Would you do me a favour and send findings like this one directly to support@vsl.co.at, please? This will make things proceed much faster. TIA!

😊 The really good ideas are always floating in the air at some point, it seems ...

You were already working on MIR 3D at the time. You probably don't remember but you replied to the post and told me. Going down memory lane: https://forums.steinberg.net/t/future-contingents-playthrough-visualizer-and-spatializer/138041

Ahhh! Yes, indeed. Thank you for refreshing my memory! :-)

Hi Dietz,

Have been experimenting with MIR 3D and I really like the new RAW Ambisonics Order 3 main microphone. However when I save a project (Windows 11,Sibelius, VEP7 server, MIR3D) and reopen there is no Audio until I switch the microphone to the default and then back to Ambisonics Order 3. Seems like a small bug. The new software is great thought. Nice Job.

Dave

Hi Dave,

could it be that the issue you seem to encounter is related to other influence factors than just using 3HO as output format? I just tested it in Nuendo, and the project re-opens as expected, with the setup I saved.

Best,

Does not work in Cubase 9.5.50

Windows Version10.0.19043 Build 19043

No matter what I do, the "server" window will not appear. I see the little rectangular panel, where you can adjust wet/dry, bypass, solo etc but not the MIR software itself with the 3d space and all the functionality to actually use the bloody thing. Spent hours trying, please help! Yes, I've clicked all the buttons.

The track is silent with the MIR inserted, when you press bypass in the MIR panel I hear the track dry, no MIR happening. not a sausage,

Cheers Chaz

Hi Chaz,

please get in contact with support@vsl.co.at - VSL's support team will sort out the issue swiftly. Please include as many information about your setup as possible, and it might be a good idea to supply an exemplary project that shows the problematic behaviour.

Thanks for your patience!

Hi there

is anyone using MIR Pro 3D on an i5 machine? Does it work fine?

I deleted the old MIR Pro plugins but now when I load a project created with the older MIR Pro Cubase doesn't find the plugin anymore so it doesn't load MIR Pro. I also tried to reinstall MIR Pro 3D but nothing changed

@Dietz said:

Make sure that you have installed the VST2 version of MIR 3D when you want to migrate legacy projects in Cubase, please.

Hi Dietz, 

I was about to write an update since I made further tests. Basically, Cubase 11 opens these projects correctly while Cubase 12 doesn't. I suppose it's because the plug-in version I used on the older MIR was a 32-bit version? In Cubase 12 I see the Mir PRO VST2 in the VST Plug-in Manager blocklisted because "32-bit plugins are no longer supported", it says. 

Just to be absolutely sure that I understand the issue correctly: Your old Cubase projects use (legacy) MIR Pro 32-bit? Then you have to make the transition to MIR 3D on Cubase 11 or earlier indeed. There's not much we can do about ...

Sounds so fantastic! I think MIR 3D is wholly the game changer of the audio history. 

Just wish the 7th roompack - outdoor stage as like forest, lake... 

Thanks a lot for the enthusiastic feedback! 😉

Ohhh yes. The recording of forest IRs has been a dream of mine since the first conceptual studies of MIR were conducted in 2002 or 2003. We have thought a lot about how to realize this idea, but so far no one has come up with a solution that would ensure that the forest is absolutely quiet for at least 12 hours - no animals  and insects, no wind, no air traffic or cars, church bells, ... Any noise that occurs during recording will introduce strange-sounding artifacts into the final IR, and considering that it takes us about half an hour to record a single (!) position under ideal conditions, this would be a daunting endeavor. (For comparison, the MIR Venue we created from Synchron Stage Vienna contains nearly 80 source positions, each consisting of 8 directions ....)

If you happen to have an idea how to overcome these obstacles, I'm all ears! 😉

Hi Dietz,

congratulation for this great product. I recently finished testing and have bought a license.

But there is an issue that should be further analysed. It is about how the Mir engine handles the dry signal. My understanding is, the Mir virtual mic polar patterns are applied to the dry signal as well. Checking all the virtual mic factory presets for me they feel like they do a spatial distortion of the spatial image that creates tension. Feels like a lens error of an image looks like.

How did I solve it? By claiming that the law of energy conservation is also valid for sound. That means, that for every angle of the mic polar patterns the amplitude square sum of left and right channel has to be constant. So I created a small python script for a simple cardioid setup with variable mic angle and calculated the StdDev from the equal power law for several mic angles.

Result: mic angle for cardioids (50% directivity, only 2 capsules for L/R, no center capsule) which leads to minimum error of energy conservation is about 67°.

Application in Mir: Concerning spatial image distortion this simple 2-capsules-setup is by far the best I have tested so far. I expect that this can be further improved by a more complex capsule design.

If someone is interested in the subject, I can provide the python script and diagrams.

Hi Vokars,

great to hear that you liked MIR 3D! Hope you enjoy your new tool. :-)

You are absolutely right that the dry signal gets ENcoded to Ambisonics before it gets DEcoded together with the newly created, positional impulse responses. The underlying idea is to match the virtual position of the source as exactly as possible with the position of the originally recorded IR (which doesn't include any direct signal for exactly this reason).

The decoding process depends on a multitude of parameters, like stage geometry, position of source and virtual mics and their angular relations, the directivity of the source signal, the number and shape of virtual capsules or the spherical coefficients. It is also important to understand that a stereo-signal is always represented as two (linked) mono-sources in MIR. Consequently, there will always be, or better: there _has_ to be some kind of imaging distortion - actually this is one of MIR's basic paradigm's. :-)

If you want to preserve the stereo image of your source by all means you should use MIR 3D as some kind of "glorified AUX send reverb": Use an AUX send from your source track to feed an AUX bus with a MIR 3D instance that's set to "100% wet". That way you will lose MIR's abilities to take care for the dry signal's positioning without sacrificing the wet signal component.

HTH,
