EAC is often used to create an exact copy of a CD which can be stored in a digital media archive or library. The goal is to preserve all information from a CD, such that the CD can be recreated from an archive and or is playable from a library. With EAC, the original audio files and a .cue file, an exact copy can be made; and with FLAC files, a lossless music library may be built. Creating an individual folder which contains the album’s compressed audio files and a cue file is done via the following method:
Open EAC and select the FLAC encoder
Insert the CD you wish to archive
If using the freedb or CTDB plugins, select the correct cover art
You may also add lyrics to each track at this point
Verify that the downloaded information is complete and correct
Convert all CD information to title case
Remove any extra spaces
Detect the CD’s gaps
Create the cue sheet and album folders
Rip the CD in Burst Mode, which creates the individual audio files
Switch to Secure Mode and re-rip tracks any tracks that did not rip accurately
This process also creates an EAC log file in the same folder.
