Audio is the sound component of multimedia. Computers (and audio compact discs and digital audio tape) work with digital audio, in contrast to vinyl disks or cassette tapes, which record analog signals.[1]
Macintosh audio history[]
The first device to digitize audio into a Macintosh computer was the MacRecorder, developed in 1985 by students of the University of California, Berkeley.[2] Starting in October 1990, the Macintosh LC, IIsi, and later models included a built-in microphone port to digitize audio, at first only in 8-bit monaural sound.[3] The Macintosh Quadra 840AV was introduced in July 1993 with the built-in capability to record and play back 16-bit stereo sound at up to 48KHz.[4]
Starting in 2006, Intel-based Macs included support for S/PDIF digital audio through Mini-TOSLINK fiber-optic connectors integrated with the headphone jacks. However, this support was phased out from MacBook Pros in 2016 and iMacs in 2017 in favor of USB and Bluetooth connections.[5]
