Hi Prem. In terms of the video production we used a master track as this film was part of the installation in the final Graduation show and was playing through the units. So needed to be a clean version of the track. The various frequencies were split between units and playing in the room. The units do themselves work with the Bass Mid and treble frequencies of the input track divided between them. They are wi-fied together and battery powered with very efficient amplifiers. The resultant (band) is really quite loud. Ben Newland designed the units which have quite complex resonance chambers. They are really very cool, the film was edited to enable people to get a sense of how they would work in the environment. Unfortunately the location we were filming in was underneath a motorway fly over and the background noise was causing problems making a continuous actuality track sync up. We took sound recordings of the units playing in the environments to enable us to recreate their interaction with the location in audio terms. Hope that explains it. Regards Chris

@chris,
sure, that explains it ... but to be honest, this way it seems a bit like a fake. I would love to hear how it "really" sounds in the environment. The actual video only shows "the look".

You say: "the location we were filming in was underneath a motorway fly over and the background noise was causing problems making a continuous actuality track sync up" .... yes, but having little sync problems would make it a documentary.
Nevertheless: GREAT PROJECT!!

Hi IRIS-A-MAZ, thanks very much for your comments, which i think are both fair and reasonable. in addition to the above explanation i would like to explain/excuse this by saying....I would have very much liked to have recorded the sound on location but we had 3 hours to shoot, no budget and little in the way of sound recording equipment that could record the actual sound from multiple locations.

The purpose of the video was to be illustrative rather than documentary. Even if we had got the sound right, the installation was going to need the original track so we would have had two different films. One with actuality and one with the original music, edited to give the effect of actuality. Again we had about six hours to edit & grade the film. We have been really excited by the way the film and more importantly the design concept has been received. Maybe we will do another this summer. Thanks again, will be checking out your stuff too.
