During the end of summer and the first moth of this second year of university, I have been doing a personal research video on Contact Microphones. Knowing that we would be developing an audio paper on the first term, I thought that it would be interesting to start experimenting with my own voice recording, and the exercise was quite helpful. For the script I was researching about the history of the contact and piezo microphones, and I also re-visited Sonic Doing & Thinking course from Year 1, where we were studying about this kind of microphone. The video explains the history of piezo technology, how it works and the main artists who use it. It was uploaded to Youtube on my personal channel, under my alias “Dasero”, my parallel project about experimental sound, synthesisers and electronic music.
