In week 7 ,we started task 3 where we have to record three instruments with different microphone techniques.We recorded Gareth playing his clarinet with the microphone in two different techniques, AB and XY.AB technique is using two omnidirectional microphones and putting them parallel to each other and  facing the hole of the instrument.XY is when we put two cardiod microphones with the angle of 90 degrees.

In week 8 and 9 we learned about ORTF technique, NOS, DIN, M/S, Blumlein Pair, Phased Array, OCT and Decca Tree.

ORTF is using two small cardiod microphones with the angle of 110° and the distance between the microphones of 17 cm that gives a total recording angle of 96°.

NOS is a similar technique.We used two small cardiod microphones with the angle of 81 degrees and distance 30 cm.

Blumlein technique is similar to XY technique where the two bidirectional microphones are facing each other , with an angle of 45 degrees.

Decca tree technique is similar to AB technique with an additional microphone in the middle of the two microphones which has distance 1 m from each.
