EAC and AAC (qaac)

Software Needed

Installation

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

  • Download the latest version of qaac - CLI QuickTime AAC/ALAC encoder
  • Uncompress the zip archive into a directory (e.g. C:\qaac). Alternatively you can uncompress just the files from the x64 directory (64-bit) or just the files from the x86 directory (32-bit) into a directory (e.g. C:\qaac).
  • Check for Apple Application Support
    If you believe that you already have the required Apple Application Support (e.g. iTunes installed) you can run this check:
    1. Open a command prompt window (press ⊞ Win+R, then type cmd and press ↵ Enter).
    2. Change directory to where the qaac or qaac64 file is located (e.g. type cd\qaac and press ↵ Enter).
    3. Type qaac64.exe --check (for 64-bit) or type qaac.exe --check (for 32-bit) and press ↵ Enter.
      A version number should be displayed.
  • If you do not already have the required Apple Application Support
    You can install iTunes.
    1. Download iTunes64Setup.exe (64-bit) or iTunesSetup.exe (32-bit) and install.
    2. Run the check for Apple Application Support above.
  • Alternative to installing iTunes
    It is possible to extract the necessary Apple Application Support files without installing iTunes.
    1. Install 7-zip, if not already installed (the script used below requires it).
    2. Download iTunes64Setup.exe (64-bit) or iTunesSetup.exe (32-bit) and move to the directory where you extracted the x64 (64-bit) or the x86 (32-bit) qaac files above.
    3. Download makeportable2.cmd and move to the same directory.
    4. Double-click on the makeportable2.cmd file.
    5. The script will create a new subdirectory (\QTfiles64 or \QTfiles) in the same directory.
    6. Run the check for Apple Application Support above.
      If all is working as expected, makeportable2.cmd, iTunesSetup.exe, and/or iTunes64Setup.exe are no longer needed.

Copy Image & Create CUE Sheet

When extracting to an Image & CUE Sheet, the Tags (artist, album title, track titles, track numbers, etc.) are located in the CUE Sheet so you don't need to tag the Image.

-v 0 -q 2 -o %dest% %source%

AAC Constrained VBR mode (Maximum Quality) with No Tags (except for the cover):
