This week we went over more of the microphone techniques we will use for the recording task, including NOS, DIN and M/S. NOS configuration involves two cardioid microphones facing outwards at 90 degrees, and with a space of 30cm between the heads. DIN is similar to NOS in that the microphones are angled at 90 degrees, but instead they are spaced 20cm apart. M/S, or Mid-Side, uses one cardioid microphone, pointed at the centre of the sound source, and one figure-8 microphone placed facing 90 degrees from the cardioid. This enables sound to be picked up from the front by the cardioid mic, and the left and right by the figure 8.
