Introduction<br />
Room Acoustics Essentials<br />
Reverberation<br />
Late reflections tend to be<br />
diffused, hence performance<br />
degradation.<br />
Beamforming: higher<br />
processing burden and high<br />
latency in STFT<br />
implementation.<br />
Deteriorates intelligibility,<br />
quality and ASR<br />
performance.<br />
Sound Fields<br />
Directional Room impulse<br />
response relates source and<br />
microphones.<br />
Uncorrelated Signals on<br />
microphone are uncorrelated.<br />
Diffused Sound is coming<br />
from all directions.<br />
