Combining Methods for Multichannel Room Impulse Response Generation and Objective and Subjective Performance Evaluation

There are many methods for deriving multichannel room impulse responses (RIR) when reference RIRs are provided. Previous articles focused on a method for synthesizing the early part of the process, dominated by discrete reflections, and a method for synthesizing the late part of the process, dominated by statistical diffuse reverberation. In order to take advantage of their respective benefits, these two approaches can be combined with a simple windowing technique with a variable transition point. Objective and subjective evaluations confirm the validity of the RIR synthesis methods and the method of combination.
