An investigation of microphone techniques for ambient sound in surround sound systems
Russell Mason, Francis J. Rumsey · Surrey Research Insight Open Access (The University of Surrey) · 1999
A controlled subjective test was carried out to assess selected qualities of three ambient microphone techniques for surround sound The effects of signal delay and microphone distance were explored. The tests indicate that the perceived results are programme dependent, but that a compromise can be found using delayed close microphones, giving similar quality for the range of programme items used.
