To find out why is the offset important Click Here
To find your write offset first we set the write offset on your drive to 0
Now get one of your retail albums you have ripped properly with EAC.
Decompress the retail album in .flac to .wav either using FLAC frontend or dBpoweramp to a random folder.
Decoding .flac to .wav in frontend
Now once converted copy the .cue from the original rip to the folder with the .wav's we have converted.
Now to write Tools>Write CD-R or alt+W
Now in the windows click File>Load Cue sheet.
Now in the folder where you extracted the .wav's load the .cue sheet you copied into that folder from the original .FLAC rip.
*If you get errors. For example Line 48 does not match you will have to open the .cue in notepad and make sure the file names match exactly it could be a space or - (dash) off. then it should work
Burn the CD on the lowest speed possible.
When the CD is done, re-rip the cd you have just burned with the same drive you ripped the original retail.
Repeat the process of converting the .flac from the burned album to .wav.
Now you should have two copies of the cd in .wav. One being retail and one being the cd you just have burned
Go into EAC Open up the WAV compare in Found in Tools>WAV compare or Ctrl+W Choose the same track (a track other than #1, so something like #3 is good) from the retail rip FIRST and choose that same track from the burned rip Second...
Now it should show something like this
Now we see that there are 30 repeated samples with this... So now to your write offset you add 30 samples +30
If it was 30(or whatever number you get) missing samples then it would be -30
