Important note

This guide is in need of an update, because in EAC 1.0 beta 2, the replacement strings changed. For example:

  • "%s" is now "%source%"
  • "%d" is now "%dest%"
  • "%a" is now "%artist%"

See the full list in the EAC FAQ or in the EAC Compression Options guide. ‎

Software Needed

Note: This guide has now been amended to reflect changes made to QAAC as of 2.76.

Installation

Note: This guide assumes that EAC has been configured for secure ripping, if not please follow this guide.

  • Download the latest version of CLI QuickTime AAC/ALAC encoder
  • Uncompress the zip archive into a directory (e.g. C:\qaac). Alternatively you can uncompress the chosen QAAC version (include qaac.exe for 32-bit, include qaac64.exe for 64-bit) into the same directory as EAC.

  • Open EAC and insert a CD into the drive.
  • Click the EAC menu and select Compression Options.
  • Click the External Compression Tab, and put a tick in the box for use external program for compression.
  • Change Parameter Passing Scheme to User Defined Encoder.
  • Change Use file extension to .m4a if not already that.
  • Click the Browse button and locate the qaac.exe or qaac64.exe that you unzipped earlier.
  • Remove the ticks from Use CRC check and Add ID3 tag.
  • Tick Check for external programs return code.
