I have, together with the Dutch sound artist Cilia Erens (she’s the real expert), done a simultaneous binaural event for about 50 people with a relatively simple FM wireless headphone system, about 10 years ago - so old technology. I think they were sennheiser wireless headphones. The hassle was checking the headphones each performance for tuning and volume level, the controls of which were on each headset. thick walls would be a problem though. You could try running antenna wires throughout the space? Don’t know if that would help. > > I've been looking at silent disco type headphones but have concerns about > the quality and also that the signal apparently is converted to mono then > back to stereo during RF transmission. Anyone tested these? FM stereo transmission does this anyway doesn’t it? as far as I remember it’s broadcast as a M/S signal. A mono receiver just picks up the M signal. A stereo receiver matrixes them together. The audio bandwidth is limited to enable both channels to “fit” into the frequency slot. Binaural recordings still work OK on the radio, even with nothing above 15khz! best wishes, Justin Justin Bennett jus...@justinbennett.nl www.justinbennett.nl http://jubilee-art.org/ _______________________________________________ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound - unsubscribe here, edit account or options, view archives and so on.
