Stereo Localization (2)
Spot Mic: 2 feet away from pick-up place
*Phase cancellation is biggest problem in stereo miking
Phase ‘pulling’ reaction to diaphragm ==> ‘Negative’ voltage
Phase ‘pushing’ reaction to diaphragm ==> ‘positive’ voltage
*Poor phase coherence: sound wave reaches each Mic at different phase of cycle
*Critical distance: the point where the direct sound is equal to the reverberant sound in intensity
To avoid phase cancellation:
(Refer to: http://lossenderosstudio.com/article.php?subject=11)
i) X-Y technique
ii) Blumlein technique
iii) M-S technique
: Mono switch —> Complete cancellation of ribbon Mic L & R (do not touch Mid sound)
: Matrix
