Double MS recording
Audio recording technique From Wikipedia, the free encyclopedia
Double MS recording is an audio recording technique used to record surround sounds using three microphones. The mid mic usually a cardioid mic, the sides using a figure of 8 mic, and the rear using another cardioid mic. This is usually used for recording ambiance sounds and not live music.[1][2]

- Center= Mid/Mid Mic
- Left=Mid+Side
- Right=Mid+Invert(Side)
- Surround Left=Rear+Side
