Tomorrow (Tuesday July 17th) at 6:00pm the CSC will be hosting a prof talk by Richard Mann on "Sound: From microphones to speakers and everything in between", in MC 4041. Come listen to the talk and enjoy some free food.
Abstract When you hit record on your phone how is the sound recorded? Air pressure changes come to a microphone, which converts electricity to voltage. The analog signal is digitized by an analog to digital converter (ADC), and finally stored as a digital file in memory. For playback, the process is reversed, and output to head phones or a (tiny) speaker. In a loud room does your phone distort? Can you hear the sound clearly? Phones are getting better. But what is needed to achieve professional quality sound recording?
