This update to jconvolver got me thinking... is there any kind of midi-controlled <a href="http://en.wikipedia.org/wiki/Head-related_transfer_function">HRTF</a> or <a href="http://en.wikipedia.org/wiki/3D_audio_effect">3d-audio</a> audio-mixer jack plugin available??<div>
<br></div><div>It would be cool to be able to use midi CC's to mix multiple soundstreams in 3d space using HRTF's to output a strereo image with acoustic positional cues.</div><div><br></div><div>Back in the day, you'd have to use expensive hardware like <a href="http://www.rolandus.com/products/productdetails.php?ProductId=411">Roland's Soundspace</a> , <a href="http://emusician.com/signalprocessors/emusic_srs_labs_pro/">SRS</a>, or <a href="http://www.qsound.com/demos/3d-audio.htm">Qsound</a> . Nowadays, I bet you could mix multiple channels of audio in 3d space using just a fast processor as DSP. E.g <a href="http://www.grmtools.org/index.html">http://www.grmtools.org/index.html</a> <a href="http://www.3dsoundstore.com/www-3dsoundstore-com/product-qcreator.asp">http://www.3dsoundstore.com/www-3dsoundstore-com/product-qcreator.asp</a> etc.</div>
<div><br></div><div>Seems like this was all the rage back in the day for human-computer interaction work. Nowadays, HRTFs are built into game soundcard DSPs and used for positional audio in games. However, it's not used for music, nor is it used for useful audio applications: e.g. a teleconferencing system where each participant is 3d-positioned around a virtual conference table so that you hear where they're actually sitting at the virtual conference table as their position-associated avatar activates to indicate speaking. (This was actually a research project I was doing a long time ago at HP Labs before they laid off the entire multimedia technology lab).</div>

I found it somewhat interesting to drop the demos into a sampler and have notes coming from different places. Note that your brain takes some time to process 3d; fast notes lose their "dimensionality." Sounds with long tails are easier to localize.<br>
