analog audio

Recording audio in a format of continuous vibrations that are analogous to the original sound waves. Before audio recording became digital, sounds were "carved" into vinyl records or written to tape as magnetic waveforms. See audio cable.




"Carved" Sound
Sound is literally carved into a phonograph record because the groove undulations are analogous to the sound waves they represent.






Analog Vs. Digital
The 78 RPM record (left) contains about four minutes of analog audio per side. The digital disc (right) holds about an hour's worth of CD music (CD-DA format) or 10 hours of MP3 songs.






audio cable

A cable used to transfer analog or digital signals from an audio source to an amplifier or powered speaker. Cables are identified more by their plugs and sockets than by the shape or color of the wire that is used. See analog audio and audio connections.




Analog Mini-Phone (Headphone Cable)
Found on most every portable device that outputs analog audio, the 3.5mm mini-phone socket (left) is just a small hole. In 2016, Apple was the first to eliminate this ubiquitous connection (see iPhone 7).






Analog and Digital Coax
Coaxial cables with RCA connectors are widely used for analog stereo as well as digital audio from cable boxes, Blu-ray/DVD players and other sources. See RCA connector.






Digital Optical Cable
The TOSLINK cable is used to provide an optical path from a cable box, Blu-ray/DVD player or other audio source to an amplifier. See TOSLINK.
