Sound to 3D object... sounds fun. For this bid I can spend 2 weeks for a few methods of doing that. The time and cost is relative though, can be less if a quicker option is satisfactory or more if willing to explore a range of possibilities... The task needs to be better stated: i.e. what kind of sound, how long is played, what type of 3D object (static, moving,...) what type of lighting is to be applied etc...
Kind regards,
