theres also the wirless bluetooth speakers from creative : http://www.amazon.co.uk/dp/B003MAJM4U/ref=asc_df_B003MAJM4U11695696?smid=A3P5ROKL5A1OLE&tag=hydra0b-21&linkCode=asn&creative=22206&creativeASIN=B003MAJM4U&hvpos=1o1&hvexid=&hvnetw=g&hvrand=704497245304525378&hvpone=&hvptwo=&hvqmt=
they get rid of the need for AD /DA conversions but of course they are limited by the following factors : 1. They are only stereo 2. They have a short range (5m) 3. They are useless unreliable junk totally unsuitable for professional applications (learnt from bitter experience) However the principle is there - I dont know if theres anything simililar , more robust and capable of handline more than two channels around but I guess you could use several of them with several bluetooth connections assigning routing the outputs to each stereo pair - Im not sure if you can use this. We did try to use these to make a teddy bear talk - but it was not a fun experience On 29 January 2013 11:41, Fons Adriaensen <[email protected]> wrote: > On Tue, Jan 29, 2013 at 06:45:16PM +1100, Ross Bencina wrote: > > On 29/01/2013 6:32 PM, Sven Thebert wrote: > > > the delay should be within 0.5ms. > > > > Fons no doubt has more to add, but one way to think about delay is this: > > > > speed of sound at sea level = 340.29 m / s > > > > therefore a 1ms delay is equivalent to moving the source ~34 cm. > > 0.5ms would be equivalent to 17 cm. > > > > Different panning/decode methods will have different tolerances to > > misaligned speakers. > > That 0.5 ms is just a rough estimate, based on the fact that you'd > want to preserve more or less correct phase up to a few hundred Hz, > where a decoder would crossover from systematic to max-rE or in- > phase. > > For a large installation this frequency would be set lower, > so you could tolerate a bit more.
