.EFA File Extension

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.

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.

No known program supports EFA files. If you have access to an ASR keyboard you can play it on there or you can convert it to another format with Chicken Systems Translator.

Chicken Systems Translator can convert EFA files to several formats. For example, Ensoniq Disk Tools can convert EFA files to the following file types:

• .WAV - WAVE Audio File
• .MIDI - MIDI Music Data
• .SMF - Standard MIDI File
• .AIFF - Audio Interchange File Format
