I burned a continous CD in TAO by accident… Is it possible to remove the standard 2 second gap automatically?

Best possibility would be to extract all tracks with a read offset of -5000 and then load each track into the EAC WAV editor and use “Remove leading and trailing silence”. Then you should be able again to write them without gaps. It would be possible to remove them also by offset correction and gap detection, but for that you would need and use the exact combined offset of the writer.
