What is an EFA file?

An EFA file is an audio file used by the Ensoniq Advanced Sampling Recorder (ASR), a digital music production studio released by Ensoniq in the early 1990s. It stores sound data in the proprietary EFA format.

More Information

Ensoniq released the ASR in 1992 to improve upon the Ensoniq EPS and Ensoniq EPS-16+ samplers (one of the improvements was the addition of a floppy drive). Ensoniq discontinued the manufacturing of ASR in 1998.
