That's what I'm looking at this very moment:
Now all you need is to replace the Room Tone with sounds of the audience coughing at the worst possible moment in the music and we'll have ultimate realism.
This would be the easiest library to record. Just hire 300 people and tell them not to make any noise whatsoever for 2 hours.This would be the easiest library to record.

And I will bring this one to the session!

Absolutely gorgeous! Makes the already beautiful venues even more so.
I hope that there will be some more sophisticated wood and fabric textures for the seats. Haha, just joking. 😄
Or to push it even further: I stumbled upon this video and love the 3D presentation of the instruments (without people). Would look very cool in MIR ...

The website is also good for those who wants to know more about ambisonics.
I have been thinking often about MIR 3D and I need to ask a few questions to see if I can get a better idea of what to anticipate and how it will integrate into my mixing plans. Dietz, if you can't answer at this stage, I understand, but I'm curious nonetheless!
So,
Will it be possible to open older mixes done in 2.0, 5.1 etc. and retain our 2D staging placements in the new MIR 3D? Will it be relatively painless to convert older MIR mixes into 3D?
What mix formats will MIR 3D offer? Are there any plans to integrate with Atmos or other object based mixing?
Thanks for your interest in our developments!
MIR 3D is still work-in-progress, so there might be changes in the feature set in general or specific changes I can't anticipate, but since you asked, I'll try to give you an idea:
- MIR 3D will based on 3rd order Ambisonics throughout its whole signal path, but of course you will be able to decode in 1st order like MIR Pro does, too. We plan to allow for a painless transition from MIR Pro to MIR 3D (not the other way round, for obvious reasons).
- There _will_ be sonic differences for several reasons, so if you need bit-identical recalls you will have switch back to Pro. 3D and Pro can't coexist side-by-side, otherwise there would be no straight-forward way to migrate existing templates to the new version.
- Format-wise the sky is the limit, from a technical POV. :-) MIR 3D will enhance the existing concept of "capsule-based" decoding (i.e. the individual capsules of the virtual microphone arrays we have in MIR Pro) with an approach that could be called "coefficient-based decoding". The latter can be seen as a way to sculpt and organize the Ambisonics output from a loudspeaker-perspective rather than a microphone-perspective. Sounds a bit confusing, I know. 8-) ... In general, things get _really_ complex quickly when dealing with HOA, so there will be (or better: will _have_ to be) Output Format Presets to deal with multi-channel mixes.
- These output formats will include all typical surround- and 3D-configurations, some of them maybe even in several flavours. MIR 3D will also be able to deliver the un-decoded Ambisonics audio stream, which opens whole new areas of use-cases. But MIR 3D can _not_ output Dolby Atmos-metadata. You will most likely integrate its chosen, discrete multi-channel output in form of so-called "beds" with your Atmos mix. There are no moving "Objects" in MIR Pro, so that's a non-issue for now.
- A final word of the notion "3D" in context of MIR: As you all know, MIR is based on impulse responses from real halls. IOW: If there was no IR source position, then there's nothing we can put a signal in. Of course we found ways to interpolate and do some other nice trickery, but please keep in mind that this is _not_ an algorithmic reverb engine, so don't expect the option to have a singer flying through the hall. ;-) MIR all about a holistic, enveloping presentation of real (!) rooms and the way instruments (or other sound sources) interact with them.
... let me repeat that this info is based on the most recent developments, but things still might change for the actual release version!
Thanks again for your interest! Highly appreciated.
I haven't understood a single word, but I'm looking forward to it nevertheless, haha. XD
Depending on the chosen decoding method the difference ranges from "subtle" to "dramatic", even in stereo. :-) It's not so much about "depth" per se, more about enveloping and also about decorrelation.
... but then, MIR 3D is not "just" about Higher Order Ambisonics and 3D audio, but also about new concepts of preset creation and management, and of course an overhauled GUI. :-)
Thank you Dietz :)
Your answers are actually very similar to my speculation, so I feel on track with my conception of what you are up to.
I have been trying out various configurations for 3D audio, including Atmos and I am finding that when I import mixes to work on that use MIR pro as the anchor for all of the placement duties, I do not have an interest to pull it apart to upmix. The space sounds so good in stereo that upmixing techniques aren't quite satisfying and I hesitate to use any "tricks" on it.
I will be happy to be first in line for the upgrade :)
I'm also very much looking forward for this... and crossing my fingers the upgrade won't be expensive 😳
It may be soon to ask but if I upgrades to MIR 3D can I switch between it and pro(24) for different projects?
Also, in contrast I've been eyeing Spat revolution essentials and I'm wondering in terms of virtual space will MIR 3D also offer some kind of "neutral" space without much of a room\venue feel to it?

Dietz,
If you have the time and inclination, would you be willing to elaborate on what you mean by enveloping and decorrelation? I think I have an idea of what you're talking about, but I'd love to hear more specifics on it so I can better understand all of this (and apply that knowledge in my own work).

"Enveloping", "decorrelation" ... That's techno babble 😊 for the feeling of being "surrounded by sound" (or in our case: by the room).

HTH,
Thank you, Dietz. Those links help me understand the concept better 👍
