Task 1: Recording in different locations using different microphones. 
For this task we were recording an acoustic guitar in different environments/locations. We recorded using two Shure SM58 microphones in a stereo setup, and a C1000s microphone. We recorded in locations of a recording studio, a big hall room and outside. We recorded these using an Olympus LS100 recording device. To set up this equipment we had to use two mic stands for the 2 Shure SM58 microphones, and wire up the two mics to the Olympus recorder with two XLR cables, and then set the mics facing down on the sound hole, and then recorded someone playing the guitar. This was for the stereo recording. We did this exactly the same for the C100s but only used one mic. 

Here is the track list of our recordings:

Task 2: Recording different instruments in a recording studio. 
For this task we were in a recording studio, Recording different instruments on different microphones. The microphones we used were: Shure SM58 (dynamic), Rode NT2-A (condenser), AKG C1000s (condenser) microphones. And we used the same recording device - the Olympus LS100. We recorded using these microphones, and we recoded a tambourine, keyboard, guitar, cymbal and a bongo drum.

Evaluation:
With all the recordings in the different locations, the recording in a small room environment was the loudest. This would be because the sound is condensed and the sound waves bounce off the walls a lot faster as the walls are very close together. Within the big hall room environment, you could slightly hear the echo, and it was quieter due to it being a big room. The outdoor recording was more muffled than the others. This is because we had nothing to block out the slight noise of cars and wind, and also sound travels a lot further.

The C1000s microphone is mainly used for recording instruments, and is not used for vocals. to record vocals you would use a Shure SM58, or you could use the Rode NT2-A. The Shure SM58 did not pick up instrument sounds well but was very good for vocals. The Rode NT2-A was good but it didn't pick up sounds that well outside.  

We used two polar patterns in our recordings, Cardioid and Omnidirectional. Cardioid is one of the most sensitive at the front of the microphone. A microphone being sensitive means that it is easier to hear a whisper from the front, but you will barely be able to hear someone talking from the back of the microphone. This pattern is more resistant than the omnidirectional pattern. This makes the cardioid pattern more reliable for using on stage. Omnidirectional has an equal sensitivity and output in all angles of the microphone. This microphone can pick up from all directions. A disadvantage of an omnidirectional microphone is that if it is by a PA system or speakers then it can cause feedback. Supercardioid has a more ambient sound and has a narrower pickup to it, even though we did not use this.
