This page is a compression gude for configuring Nero AAC encoder with EAC for greater encoding flexibility. This guide will allow you to create Nero AAC files that will be compatible with ITunes and your IPod or any other digital audio player capable of playing AAC files.

Software Needed


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

  • Unzip the chosen neroaacenc.exe build into the same directory that EAC is in (Note you can use regular build or the SSE optimized version that comes in the zip file).


  • 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 check box in use external program for compression.
  • Change Parameter Passing Scheme to User Defined Encoder.
  • Change Use file extension to .m4a

Note: Remember to use .m4a extension so that ITunes can read your metadata tags!

  • Click the Browse button and locate the neroaacenc.exe that you unzipped earlier.
  • Remove the ticks from Use CRC check, Add ID3 tag and check for external programs return code.
  • In the Additional command line options box, copy and paste one of the below strings based on the Tag you would prefer.

No Tags:

-q 0.5 -if %s -of %d

Metadata Tags:

Note: The information is below is incomplete and needs to verified correctly

path for compression: C:\Windows\system32\cmd.exe

additional commands:

/c C:\path\to\neroaacenc.exe -q 0.425 -if %s -of %d && C:\path\to\Neroaactag.exe %d - meta:artist="%a" -meta:album="%g" -meta:track="%n" -meta:title="%t" -meta:genre="%m" -meta:year="%y"

You need to substitute path and to to wherever you have placed the executable above. The above code invokes the windows command-line and tells EAC how to properly encode and tag your files. You can replace the -q value with a value from 0.05 to 0.95 (any fractions in between are acceptable) for what bitrate corresponds with what quality level read here
