The proliferation of computer-based acoustical data acquisition instruments, which store room impulse responses on magnetic media, suggests that some uniformity and interchangeability of these data would be beneficial. For example, a central, accessible public-domain library of room impulse responses would allow practitioners, researchers, and educators the opportunity of applying their respective post-processing techniques to any of these uniformly stored data from venues around the world. Suggestions are given for headers, data structures, and trailers based on current practice for two systems. An example of a data translation exercise from Ram-Soft-II to MLSSA is used to emphasize the need for a standard.
