The convolution based Space Builder employs segments of impulse responses to construct flexible spatial designs using an intuitive graphic interface. The system uses multiple low-latency convolution engines loading data from a library of multi-channel impulse responses, a 128-channel MADI router and mixer operating at 24/96 resolution and a MIDI controller. The controller reveals different levels of complexity depending on the needs of the user. The design, architecture, and functionality of the modules and the system are described. The system provides spatial up-conversion from 1 to 24 channels and has capacity to expand the number of channels beyond 22.2. Future applications for the system, including live sound applications, will be presented.
