Assistive mixing system and method of assembling a synchronised spatial sound stage

Oldfield, RG; Shirley, BG

Abstract

To permit contextually relevant sound events, such as blowing of a referee's whistle, to be identified, selected and broadcast in a time-delayed audio mix, FIG. 1 shows a system in which multiple directional microphones (DM1-DM12) capture sound events (16-20) from a specific location (14) within regions of a stadium (12) covered by each microphone (DM1-DM12). A processor (34) executes signal processing and sampling of captured sound events on each channel. The samples are compared to reference feature templates (152) corresponding to pre-identified sound events stored in a database (40). If the comparison of samples to the feature templates shows a correspondence, then corresponding buffered audio is introduced into the final audio mix. Sound events can be placed spatially relative to other sound events. Additional automated audio processing may augment or modify the original sound event for each channel when inserted into the audio mix.
