Multichannel Room Impulse Response Rendering on the Basis of Underdetermined Data
With the widespread interest in spatial audio reproduction, this study explores an innovative way of creating and distributing spatial information corresponding to a mono or stereo archival recording in a real space. An arbitrary number of room impulse responses can be generated from the time structure of one or two reference responses by extracting an approximation to the geometric structure of a reference space. The early reflections are examined to extract the initial reflections from the floor, ceiling, and walls. The remaining scattered and diffused sound is modeled as scattered point sources. Estimates of such parameters as room volume, source–receiver distance, and incident direction of the direct sound are possible.
