Hi Richard - Ive also being using the leap a lot - its great but a bit
buggy sometimes when you get outside the infrared area , you can see it
used in a big neolithic site here :
https://vimeo.com/217058501
I had a friend who used the connect
Kinect... ;-)
According to J. Joyce and if I remember well, you "can connect a Kinect
but you can't kinect a Connect".
8-)
which was also fine but a bit buggy.
Nothing is perfect. (Sigh...)
Best,
Stefan
Do you have a link to the stuff you did with the leap ?
You have to Jump! (s. Google)
anyway yes Ill message you near the time ,
best,
Gus

That’s an inspiring video, thanks!
And many points of contact. A few years back we used the Microsoft Kinect
to allow for hand control over sound localization, much like you appear to
be using the wii in the video. This worked well, except for the fact that
the user had to be positioned in a fairly confined area. The mobile device
control removes this restriction.
Last year we used Unity and the Oculus with the LeapMotion controller to
create a virtual room and move ‘grabable’ sound sources around it. We tried
providing the audio over headphones using Unity’s capabilities, and also
Immergo (DBAP) over speakers. Interestingly the test subjects preferred the
external speakers.
Yes, I have used the phone’s orientation capabilities to indicate a
sound’s localization, but don’t have a video of it. You can see the layout
on the phone here:
https://www.immersivedsp.com/ <https://www.immersivedsp.com/>
Checkboxes at the bottom select the various axes. The purple circle can be
touch-moved for two dimensions, and the white rectangle indicates
height.The blue circles indicate already recorded tracks that move with the
playback of the sound.
Would love to make the London demo and if possible will contact you,
thanks!

by the way have you already done this thing pointing the phone and
indicating a sound in 3d space - if so do you have a link to it ?
This is a pretty crappy video of very early prototype I did a few years
ago
- but things have moved on a lot since this :

That sounds great Augustine, and fun! Certainly highlights the
flexibility
and capability of Max/MSP.
Immergo uses the gyroscope of the smartphone/tablet for orientation
determination.
The typical mode of working is to touch-move a sound source (circle)
around a representation of the sound space on the screen, for two
dimensional movement, and to tilt the device at the same time for the
third
dimension. You can request that all three axes are provided by phone
orientation though. So then it would be like pointing the device to
indicate the location of the sound.
The rendering algorithm is selectable - DBAP is used for unusual speaker
arrangements, like an art installation ’tunnel’ that we are currently
setting up. But you can select VBAP if the speakers are arranged on a
sphere. Big thank you’s to Trond Lossius and Ville Pulkki who made their
algorithms freely available!!
A long overdue and pleasurable task is to use Max with Immergo.
Currently
using the Reaper DAW. I will keep you updated.

Thats pretty impressive Richard - I would definately consider this
system
in future for indoor stuff. In terms of interactive and automation - I
do
that in MaxMSP mostly - so we have things like an accelerometer on your
hand and wherever you point there is a sound etc etc - you also have a
map
of the speakers and pan around that map (using Dbap basically) - Ive
seen a
lot of third party systems that do automation etc - but I am already
pretty
happy with max for interactive 3D audio - theres nothing Ive found I
couldnt do yet ! But I guess I could integrate max easily enough with
the
AVB system.

One other thing - you mentioned wanting to move audio channels in real
time - you can move up to 32 channels around in the speaker space,
using a
client-server program called Immergo. The server runs on the Mac and
the
client on the Mac or a remote tablet - its web browser based, so you
type
in a URL. You successively select tracks and move them around a
representation of your speaker space. You can record and play back the
movements. The movements are realized via mixer matrices in the
speakers.
So its two different approaches you can use - pre-prepared channels
with
movement incorporated (guess you would use the terminology ‘bed
channels’)
or channels that can be moved via the mixer matrices (object audio
style),
where metadata containing time stamped 3D coords is recorded.

That’s correct Augustine - just the Ethernet out the Mac. That will
go
into an Ethernet AVB compliant PoE+ switch (extreme, netgear etc).
The SPK-4Ps will be connected to other ports of the switch. You can
link
together switches for larger port numbers.

Hi Richard -

Hi Augustine, to answer this question about the SPK-4Ps:
can you daisy chain them (as discrete channels) or would you have
to
run
a seperate ethernet cable to each one?
You would run a separate Ethernet cable from a switch to each one.
So
for
example, running a DAW on a Mac, you would output your tracks to
the
outputs made available by the Mac AVB virtual audio entity, and
each
speaker would listen to one of the outputs.
You would use PoE+, not PoE, and each speaker is powered by a Merus
audio
Eximo amplifier, providing 30W. With the Mac you could connect up
to
120
speakers. You also have the possibility of connecting a separate
passive
speaker to the powered one, providing 2 x 15W.

aye - and that would kind of defeat the advantage of it - Ill
stick
to
passive for now - Ive always found active speakers a bit of a pain
for
larger site specific stuff because you have to run power to them
as
well
as audio.
These look like they might be OK for some stuff :

but Im a bit unsure as to what exactly they can do - can you daisy

Hi,
I think that you'll find that an active speaker with an AVB input
will
require more current than can be supplied over an ethernet cable.
Perhaps
for very small speakers with a low power digital amplifier, but
anything
decent would require mains (or DC batteries) to the speaker.
The available current may power the DAC though.
Ciao,
Dave

Subject: Re: [Sursound] Multichannel players for permanent
installations
Hi Richard -
There is lots of things that pan all around the room but the
soundscape is
designed in pre production for this installation and then its
just a
multichannel file (or seperate mono ones). Other installations I
do
are
interactive and so sounds are processed and panned in realtime
around
the
space depending on the sensors used etc. Certainly the AVB thing
might
be
good for some less inhospitable environments- I especially like
the
way
power can be taken to the the speakers via the ethernet
cable.....
