Using various different types of microphones, we recorded sounds around the London eye area. I made use of a contact microphone, placing it on coregated steel mesh floor and whilst stamping allowing the microphone to catch the reverberations which i have used in my piece. I also used an electromagnetic mic that picked up the electromagnetic microphone that allowed me to pick up electromagnetic signals in electrical objects. I made sure to pick up more metallic sounding sounds for my peice as that is what it is based on. I found it interesting the way in which different microphones interacted with different environments and how some where better for picking up some sounds that others.
