Frank - you're very welcome. The worst thing that can happen to a VSL forum member is that I politely point her or him to a certain page of the manual ;-) ... and some people will agree when I say that I'm able and willing to put on the emergency brake when things _really_ get out of hand (but we are far from that point, rest assured).

Everything else is interesting both for fellow users and developers.

Kind regards,

 Nice to hear. Even though I will try not to carry coals to Newcastle. :-) 

Hi all, hello Dietz,

in my last little experiments -  :-D - I've used for the hotspots in the "Großer Konzertsaal" the main mic wide-cardoid  r e v e r s e  (actually for the Foyer). Is that a wrong choice for this venue? (Didn't notice any dissonance - coming from the reverb...) 

I noticed by the way, that the hot spots in these venue are available only with two main mic positions conductor and 7th row. What's the reason for that? So I'm thinking these nice places on the balconies couldn't used for a great dolby surround set up? (I don't have it (yet), but just thinking about, what could be possible - for some special kind of sound art design.

My other experiments to get more and more familiar with MIR I used selfmade main-mic setups. I can do it by try and error only, I noticed you can get with the left-right distance parameter a "more deeper" space-impression (hard to explain what happens, it's more psycho-acoustical). But how to use it in a more controled way?  Probable by experience, I'm afraid. (Seem's to me increasing the left right distance is great to use for bigger ensembles.)

I've tryed out the new teldex venue to use for ERs only (trimed to 1.12 s), and the rendered single tracks to give a vintage plate hall tail.  1.12 s it's quite a lot for the ER's, but what do you think how much of trimming the reverb make sense for these venue?

So thanks in advance for every helping reply!

Frank

Whew, lots of questions. 😉

Errr ... my understanding of _early_ reflections encompasses more the 0.1 - 0.3 s range ... everythin else is just reverb 😉

I know that the idea of using "ERs and adding algorithmic reverb" is floating around the Internet since quite some time now, but I'm still not convinced that the approach is one I would choose. Personally I would rather add some nice Lexicon or t.c. to the whole mix than trying to cut out the tail from the impulse responses (... for me, the reverb tail is as important as the so-called ERs, but that's a different story).

But you know - "If it sounds right, it is right!" 😉 ... as long as _you_ like what you hear, it's ok!

Kind regards,

Yes, a lot of questions, I know, thanks again for your kindly reply!

To the last point: Always I've thought that these white spread talking gibberish of "ER" and "Tail" in truth and actually is a blend of two reverbs. Sometimes the predelay (=ER) for the tail is set to zero, but anyway. So I'm using these fogged words too.  

Listen to the really incredible sound of the studio rooms of MIR I got inspired to make a old fashion set up, a virtual studio recording in one of the roompack 2 studios to give on top an old common algo-reverb - (I use a inserted hardware t.c.). It's not what I'm aiming for normally, but the idea behind of those setups for me is to get a special "sounds of common remind". I call this "idioms" to use for quotes, so to speak using a sound for a sign of a period. (I try to compose sometimes in this way, trying to avoid the common crossover, more in a way of rigorously switching, so the sound of the reverb can help a lot to make it clear and convincing, and MIR is inspiring a lot on this way.) Thats why I try to simulate the old recording way.

Thinking about what they did formerly (different in each period for shure), how much of reverb information coming from the original recording they have used in the final mix and how to simulate such things, I thought it could be useful to cut out the reverb tail for a better blend. It's good to know a tenor opinion about now.    

So thanks for your pieces of advice!     

Kind regards

Frank

[...] predelay (=ER) [...]

No! Predelay is the time _before_ the first and all the other early reflections arrives at the point of the listener. The longer the predelay, the farer away any reflecting surfaces are. - The problematic part about this concept is that it treats a source as flying object, because more often than not the fact that the first reflecting surface is the floor is simply neglected. 8-)

So working with MIR makes my day! (the floor shouldn't be the problem anymore? : - )  Yes, I remember, read about making the distant with value of initial reflection etc...absorb behavior of concrete or influence of humidity for sound propagation...or damping high frequencies for farer away sound sources... [8-|] I'm geeKing too. But seems it hasn't any effect on me. LOL  

Didn't care anymore since working with MIR, forgot it and now all it's got into a mess. 

So I will do my lot of absurdism using rather emotions than reasons to express my heartstrings.  

To be serious finally: Thanks for rectification!

Best

Dietz, I was wondering if you could explain more about why you chose the ORTF mic arrangement to record the library, specifically I've posted a couple of years back complaining about finding coherency problems when using Altiverb and large mixes, (specifically that I found that convolution seemed to exacerbate severely coherency issues in the mix to start with) that I couldn't fix. I found the new panning tools greatly fix that, and a test on the MIR trial last week I found that coherency on a medium sized mix was very good (I heard this, and I dug up my Waves Analyser which has a stereo coherency meter) it seemed very good. I remember vaguely this was explained as a future proof method - on the surface ORTF is not a great source for panning and altering of stereo width en masse, but with proper treatment it's actually the best way to do it, leaving maximum flexibility later on - almost as an archival technique, so to speak. But can you speak more about that, I'm really interested in technically why it works so well with MIR, and so badly with other convolutions - not just Altiverb, but all other convolution reverbs as well as simple panners, and even without reverb large mixes with lots of panning and width modification (when not using VSL panning). What is the technical science behind that? (without going into trade secrets!)

I'm not going into the discussion pro /contra ORTF recordings of instruments again ;-) ... but one of the main reasons why MIR / MIR Pro works _at all_ is that any positioning-relevant processing is done in Ambisonics. All IRs are recorded in 4-channel format A and later transcoded to Format B. All dry signals are encoded to Format B. MIR's Output Format (i.e. the Main Microphone) defines the decoding.

This is also explained in MIR Pro's Manual Addendum "Think MIR!" -> http://dl.vsl.co.at/downloader.aspx?ID=7629

... so - it could that you simply like the way how Ambisonic handles "panning". :-)

Kind regards,

Hi Dietz, I'm sorry - where was that discussion is there a link? I couldn't find anything... ? Was that discussion with me? [*-)]

Yes I've read the addendum - very interesting everyone should take a few minutes to read it.
