Gap Technology
EAC is able to to detect pre-track gaps. These are the pauses between two tracks. Usually they are two seconds long and a CD player will display negative timings during this pause. By using the command “Detect Pre-Track Gaps” it is possible to detect all gap-lengths by reading the sub-channel information. As this information is not stored on the CD directly, EAC has to search for the position where a track ends. This search is usually quite fast, but it still will take on average a second per track.

You can choose to add the gaps to the previous track (which is how other rippers will usually extract tracks). Otherwise you can choose either to append the gap to the correct track or to leave it out. A benefit of performing the detection and getting the gap times is the possibility to copy a range. That way the correct times will be displayed in the copy range dialog.

Please note: Because the pre-track gaps are determined by looking up CD positions, it is possible that it will not be 100% accurate. But in most cases it will be correct, the deviance should be lower than 2-3 sectors.
