The Society of Professional Audio Recording Services, or SPARS for short, is an organization that holds conferences and publishes papers about the professional audio community. Its members include many of the top audio engineers working in the industry today.
SPARS also developed the SPARS Code which was common on the back of CD covers from the late eighties to the mid nineties. It specified whether analogue or digital recording mediums were used in each process of the recording.
