Abstract:
The Room Impulse Response (RIR) has a major effect on what we hear, whether it is in an arena, recording studio, cathedral or home movie theater. It is the “DNA” of room acoustics, allowing us to see and analyze how a room or space is affecting the sound that we hear. There are many ways of obtaining an RIR ranging from gunshots to log sine sweeps and binary maximal length sequences. Which is best? Should we use an omnidirectional microphone or binaural technique? Or even multi-microphone arrays? How do you process the data? What does the data mean? How do speech intelligibility, clarity, and STI relate to the impulse response? Which reflections are useful and which are detrimental?
The workshop aims to answer all these questions and will also show participants how you can hear the measured Room Impulse Response and how this can be used to diagnose and help remedy room acoustic or loudspeaker location problems. The international workshop panel has a wealth of experience in the measurement, analysis, and interpretation of RIRs and will be letting you hear as well as see what the RIR is all about. The workshop is therefore a “must hear” event if you have anything to do with room acoustics, sound systems or setting up audio systems.
