A/B Stereo Mic Technique



優點是靠近錄音源的話，錄音效果會非常好
缺點是立體定位不好，周圍的訊息也會損失

A/B is the most simple stereo technique to use. Quite simply, two microphones are pointed straight ahead at a source. This technique sounds surprisingly good on acoustic guitar and very close to the front while recording live; however, there's not much stereo image, if any, and a lot of ambient information is lost.

A/B is the preferred method of tapers who stack tape - taping close to the speakers to get a cleaner sound. However, A/B isn't as useful for taping further back, as a good stereo image is necessary for full reproduction of the event.
