Not crop, but you have to click on the link and
enter your e-mail address and sursound list

Depends on where you are located. Here in Europe it's the equivalent of
650 USD. The usual margin of 3 percent our importers scrape their meagre
living from...


Given I have access to a variety of higher price point options...


...you should be the ideal candidate for doing a comparison. :-)

Re: [Sursound] another mic -

2020-08-24 Thread Joseph Anderson 
Hello Jim,

I've recently received the one ambiMIK-1
<https://www.minidsp.com/products/acoustic-measurement/ambimik-1> I
ordered. I haven't had a chance to put it through its paces yet, but
installation on macOS is fairly simple and straightforward.

My first view is that it is perhaps most useful in a measurement
context, which is the manufacturer's intention. As the device is USB
powered, long cable runs for making live "in situ" recordings are probably
not advised.

Things I do know:

   - easy to install
   - easy plug-n-play
   - very accessible price point


Things I don't know yet:

   - noise floor
   - spatial performance


Given I have access to a variety of higher price point options, I expect
I'll likely think of it as a quick "point and shoot" option


My best,

Dear Groupe,
i'm a longtime reader but first time poster to this wonderful email list,
and I am still pretty new to 3d Audio so I would be grateful for some of
your knowledge and experience.

We are planning an immersive audio-video Installation that is supposed to
be in a 4 x 3 x 3 meter room. 3 walls and the floor will be projected onto.
The Sound should come from all around the room (right now we are thinking
about a rig of 12 speakers on ear-height, 4 on bottom layer, 4 on top
layer, 1 voice of god and 4 lfes). Unfortunately quite a lot of the
speakers need to be projected onto and ideally they would hide in the
drywalls seamlessly without compromising the sound quality. So my first two
questions are (probably quit a few will follow):

1) What are your suggestions for hiding the speakers? Do you have
experience what fabric or cinemascreens would still work well (regarding
that the room is rather small and the audience can move freely and might
come pretty close to the walls)? Are there any other methods that i'm not
aware of?

2) How crucial is the sweetspot and is there a possibility to widen it by
the choice of speakers and/or speaker layout without losing too much
spatial resolution?
The room is rather small, but still we expect the people to move around in
it, since their positions will be tracked and interact with the content of
the installation.

Thanks a lot in advance, this mailing-list is a wonderfoul resource. :)
I hope you all are well.
All the best,
Max

Dear Max,

check out the configurations we use in our Immersive Media Lab at 
Hannover University.

(https://www.ikt.uni-hannover.de/forschung_iml.html)

Its described in detail in the publication I append.

When you have additional questionss feel free to contact me or the

Re: [Sursound] Speakers for an immersive audio-video installation

2020-08-24 Thread Augustine Leudar 
A couple of years ago I did an 3d audio installation with unity . We sent
OSC between max msp and unity and did all the audio in max. I've done
similar things with open frameworks and I'm working on something with touch
designer at the moment. Personally I'd want to be doing the audio in
dedicated audio software like max communicating via osc.
