    Hi!

    Is it possible to simulate crosstalk between channels? (as it exist in real life):
    For example, we have 3 instruments: piano, flute and violin.
    piano mic recieive not only piano signal, but also little dry/wet signal from flute (with delay, related to distance to piano mic and eq/volume, related to piano mic direction type) and from violin (with different delay and volume/eq)

    And same with each microphones - flute mic receive a little bit of piano and violin sound, violin mic receive a little bit of piano and flute sound.

    It is very serious option for achive real orchestra sound mix

    Best regards,
    Vadim

    I think you misunderstood the concept of MIR a bit. MIR let you position not primarily microphones for each instrument but the Sources of Sound in the Stage from which the acoustic reflections in the certain room (venue) will be calcutlated seperatly. All seperate calculated sources with their individual acoustic reflections are recorded from one wet Microphone-position (which you can only mix with the Dry signal). You can only define the position of that one microphone in the venue which records all sources you have positioned.

    In short there are no seperate microphones for each instruments as you put it in so far there is only one microphone which records all events together and not any individual instrument for each inytrument which might record reduced parts of the others as you described it.

    I always thought it would be the in a strict logical sense necessary extension to combine Synchron and Silentstage-libraries to have also multiple microphones available in MIR. But it seems to be that this would make the handling of MIR that much more complex and obviously acousticly even instable that Dietz indicated that meanwhile they have experimented "indoor" with a MIR-based software which seems to be able to do that, they do have no plans at all to develop that for the market in any way.

    No, I am understand (my profession is soundengineer 😊

    I am understand, that we have no individual microphones, but: in MIR we have sources of sound - incoming signals (instruments). We can select an instrument profiles (and mic capsule type) for these sources - it's already exist. All's need for crosstalk simulation is to add (mix) a little bit of other sound sorces to each source before adding a hall impulse, correct me if I'm wrong.

    Dear Vadim,

    it might be that you're indeed misunderstanding the concept of MIR Pro's "Instrument Profiles" a little bit. We're not trying to mimic actual spot-microphones for the dry signal component here, but rather the typical sound emanation of individual sources.

    I know that the "General Purpose" profiles are a bit misleading due to the fact that we decided to use familiar descriptions (like "Cardioid", "Omni" etc.) for those generalized emanation patterns. You have to understand them like descriptions one would give for a loudspeaker, not like the polar patterns of microphones.

    ... that said, I hope it is obvious that there is no cross-talk between individual sources. 😊

    There's a little add-on to MIR Pro's manual, called "Think MIR!" available in your "MyVSL" User Area. It tries to cover basic concepts like this, although in a colloquial, informal way - please don't expect a full-blown technical white-paper. ;-D ...

    Kind regards,

    Hi Dietz,

    yes, I have read this PDF) I am understand, that at this point this purpose is not possible, my question more about future features of MIR ;)

    Ahhh! So the misunderstanding was on _my_ side, not on yours. :-) Sorry about that.

    Right now, we have no plans to mimic crosstalk between individual MIR Icons on a stage ... actually I always thought that this is a major benefit, not something anybody would miss. ;-) 

    But never say never - we have quite some ideas for future updates of MIR up our sleeves, so let's see what VSL software engineers are able (and willing) to implement.

    Kind regards,

    Hehe, yes) in painting good artists add one paint in all other colors to obtain the integrity of the picture. In the sound mix, if there are no crosstalk (in other words, if we only have separate individual microphones + reverb), we obtain a group of individual artists sitting in their personal booths (with open door to shared hall), instead of the whole large orchestra. Indeed, it is great benefit, if we plan to make some kinds of music (advertisement, pop/rock and other hi-tec jenres. But if we plan to make documental calssic music records and natural space as in live, we need shared mics (as in Synchron series), or crosstalk (for Silent stage series)

    Well - in case of Vienna Instruments ensembles (like Appassionata strings) you have that cross-talk built-in, so to speak. But you're right, there is no cross-talk between solo instruments and/or different instrument families.

    Thanks for your input! :-)
