History Before 1925 all audio recording was strictly mechanical 1860 recording with charcoal and paper – https://en.wikipedia.org/wiki/File:1860-Scott-Au-Clair-de-la-Lune-05-09.ogg 1885 – Disc Phonograph incl recording of Alexander Graham Bell’s voice – https://en.wikipedia.org/wiki/Volta_Laboratory_and_Bureau#Bell.27s_voice Became the Vinyl that we know Til 1945 – Electric but still recorded onto wax discs as master Magnetic recording onto tape and became the standard after 1950 1975 – first recordings onto DAT, CD etc MP3 in 1993 Microphones Ribbon Microphones Ribbon of metal suspended between magnets. As voice moved the ribbon, generated an electrical charge Dynamic Diaphragm moves from air movement (voice etc) which moves a magnet inside a coil which generates the electrical charge Condenser Capacitance. Diaphragm moves backwards and forward towards another plate which changes the capacitance. These microphones require power. Often phantom power +48V along the same cable as the audio. Applies voltage to both signal lines equally. Audio signal is the difference between the two signal lines so does not affect the sound Recording DAWs CAST/ZenCaster Mastering EQ, Compression, Gate etc Loudness Auphonic Delivery As above iPods Radio Streaming
