Topic: Someone is using binaural mics to create impulse responses

Intended for a general audience, but the results are more than interesting: https://www.youtube.com/watch?v=onuVjhZ...e=emb_logo

This is the thread on VSTI Control where I encountered this:  https://vi-control.net/community/thread...no.103480/

I hope that he does more spaces. All cathedrals do not sound alike, but they do sound like cathedrals.

EDIT:

More, in a tiled basement and playing more piano: https://www.youtube.com/watch?v=bmOvHjSBlnc

I do not see that he has made his impulse responses available for sale.

Re: Someone is using binaural mics to create impulse responses

Interesting video, Jake. The only problem is that it only works with a binaural head microphone, and for real instruments. The binaural mode in Pianoteq tries to emulate some binaural effect, but it can't be completely realistic because it is not listening to a real environment with natural reverb that gives the "you are there" feeling. If you produce binaural recordings, using a head microphone, it certainly is a good idea to have the capacity to add binaural convolution reverb to it but I doubt that binaural impulse files used with Pianoteq would produce a better result than the current ones. But I may be wrong...

Well, for Pianoteq, could the impulses be recorded at the same time as the reference samples--in the same room, from the position of the player with the piano still in the same room, but dampened?

Did you see the second video, which ends up concentrating on a piano? I hear the effect as being too pronounced at times, but very good at other times. I wanted to be able to turn the knobs to hear what could be done.

But I don't really understand if a binaural impulse response CAN can be used in a DAW or in any current instrument. Once different signals are recorded by the different mics, can they be combined into a single file that can be loaded? Can current DAW's or instruments then "understand" the file and use the separate impulses in the left and right channels? Obviously, Matthew Lien is able to run the live sound through this reverb, so a DAW should be able to replicate the situation, but when I search for "binaural impulse response" in Google, I find several articles and no files in the usual formats. I do see a few files in what is called a SOFA format at https://zenodo.org/record/2641166#.X-oEPNhKjAQ , but I don't know what programs can use this format.

Have other people here looked into this a bit? Dragon? Joe? Philippe and Niclas and Julien and others at Modartt? Seems odd that, with the constant release of new reverbs from several companies, there is little or no mention of binaural attempts. Reverberate, from Liquid Sonics, loads two impulse responses at once, but that would require two files created with a binaural mic, and binaural recording doesn't seem to be the focus. The website instead talks about using separate impulses for early and late reverberations. Don't know if it could "play" two impulses at once for a binaural effect. I've written Liquid Sonics to ask.

Re: Someone is using binaural mics to create impulse responses

As I understand it, the true binaural effect can only be obtained by recording in a venue through the head microphone that replaces the listener's ears. What he did that seems new is use his binaural head to capture the impulses in a way that they are more natural when adding to recordings done with the binaural head. We then listen to the video where the sound is recorded from the binaural head microphone. Pianoteq standalone or in a Daw has no such capability I think.

Re: Someone is using binaural mics to create impulse responses

And Matt from Liquid Sonics wrote back almost immediately to say that:

"I’m not too sure the format you require, but if it’s a 4-channel true stereo file format in wav or flac format or two stereo IRs you’d be ok. We have a two week demo to check out if it does what you need."

Hmmmm. So all we need is one of the Neumann KU100 heads? They are $8000. Not good. But can one create a good binaural recording using a pair of cardioid mics separated by a dense enough material and placed in the same position as ears?

And would someone else please try this before I waste a lot of time trying it?

(Gilles: We cross-posted. I wasn't ignoring what you wrote. I do understand, now, the problem. Still, I wonder about the effect of the binaural impulses even without the use of the head to record the piano. Regardless, I now want to hear more binaurally recorded pianos and impulses.)

Re: Someone is using binaural mics to create impulse responses

And one of these Neumann binaural heads is now available on ebay:

Don't hesitate, lads.
