Some large rooms kind of disappoint in terms of resolution and they’re having up to 2700 speakers ( <a href="https://www.ak.tu-berlin.de/menue/research/wave_field_synthesis/parameter/en/" class="">https://www.ak.tu-berlin.de/menue/research/wave_field_synthesis/parameter/en/</a> ) - But it’s a different Technology so it’s probably not gonna be a DIY project.</div><div class=""><br class=""></div><div class="">But with Ambisonics it might be worth trying it with 4 speakers. If you have 8, even better.

It uses 176 speakers but it is possible to build installations with less, say 8 speakers using a technology called Ambisonics.

As I’m backpacking right now, I don’t have the necessary equipment to do that. So I wanted to ask if it’s possible to get access to a lot of small speakers and an audio interface with as many output channels as possible. I know these things are expensive but if anyone could spare one even for just a couple of hours, I promise to treat it well. Also, there is nothing that may damages the device. It will simply be used by a piece of software (the spatialization renderer) that sends audio to the various output channels.</div><div style="margin:0px;line-height:normal;color:rgb(69,69,69);min-height:14px" class=""><br class=""></div><div style="margin:0px;line-height:normal;color:rgb(69,69,69)" class="">Alternatively, it may be possible to to use a lot of two or four channel audio interfaces on a USB hub as an aggregated device (on a Mac). </div><div style="margin:0px;line-height:normal;color:rgb(69,69,69);min-height:14px" class=""><br class=""></div><div style="margin:0px;line-height:normal;color:rgb(69,69,69)" class="">As for the speakers, if it’s not possible to find similar speakers, a bunch of old crappy different desktop computer speakers will do.</div><div style="margin:0px;line-height:normal;color:rgb(69,69,69);min-height:14px" class=""><br class=""></div><div style="margin:0px;line-height:normal;color:rgb(69,69,69);min-height:14px" class=""><br class=""></div><div style="margin:0px;line-height:normal;color:rgb(69,69,69);min-height:14px" class=""><br class=""></div><div style="margin:0px;line-height:normal;color:rgb(69,69,69);min-height:14px" class=""><br class=""></div><div style="margin:0px;line-height:normal;color:rgb(69,69,69)" class="">Happy for any feedback.</div><div style="margin:0px;line-height:normal;color:rgb(69,69,69);min-height:14px" class=""><br class=""></div><div style="margin:0px;line-height:normal;color:rgb(69,69,69)" class="">Best,</div><div style="margin:0px;line-height:normal;color:rgb(69,69,69);min-height:14px" class=""><br class=""></div><div style="margin:0px;line-height:normal;color:rgb(69,69,69)" class="">Alex</div></div><br class="">_______________________________________________<br class="">
