Comparison of Microphone Distances for Real-Time Reverberation Enhancement System Using Optimal Source Distribution Technique

Document Thumbnail

Although musical instrument players may want to learn the spatial impressions of the concert hall beforehand, practicing in the actual hall is not practical due to the geographical and the ?nancial reasons. Hence, it is helpful for players if there is a spatial reproduction system that can recreate the concert hall reverberation in their practice environments. An implementation of crosstalk cancellation method for synthesizing virtual auditory space using loudspeakers called Optimal Source Distribution technique is used to add realistic reverberation of a live venue to a violin performance in real-time. In this research, one of the de?ning parameters for the timbre of convolved reverberation, microphone placements on and over the instrument, were compared by professional players.
