I work for a Post Production (special FX etc) company and the way we do renderfarming is we have a network of rendering machines and a renderque server.

The animator would for example want to render a 3D scene so he would tell the renderque manager to put his job in the farm.

If its a 75 frame animation sequence, the que manager will send one frame to each machine in the farm to do instead of all of them working on one frame simultaneously (which is what you are suggesting).

The way you would have to go about doing what you want to do in my opinion is to write an interfacing app which would take the sound break it up into lots of little bits, send each little bit to a machine with sufficient resources and put them back together once theyre all done as one whole sequence.

This would work in the same way as an existing and very reliable model.

Hope i've helped out.
