MUSC 2100 Lecture Notes - Lecture 1: Signal Processing, Toslink, Balanced Audio
Document Summary
Common digital audio devices: computers and smart phones can record and play back audio (although very poorly) New section 1 page 1: good quality sound work breaks the path into individual components that are dedicated to optimal performance. Devices: microphones and pickups, audio interfaces and sound cards, computers and software, monitors. Headphones and specialized speakers: cables and software, etc. to connect the various devices. Carrying three types of signal: audio (analogue/electrical, digital audio, midi (musical instrument digital interface) Audio connectors: balanced connectors require two wires plus a braided wire shield to carry a monophonic audio cable. Are able to carry audio signals over long distances without electromagnetic interference: unbalanced connectors are unshielded, and used for monophonic audio connections over short distances. Trs: balanced mono (1/4") or stereo connection 1/4" or. Rca analogue cable vs. coaxial (s/pdif: sony/philips digital. Digital connections: s/pdig and the toslink optical connector. More common now: usb midi connector (type a to type b)
