Two voice tracks can start out of sync or slowly move apart during a long conversation. These are different problems. A fixed offset means the timing difference stays similar. Drift means the difference changes as the recording continues.
Compare three points
Find a clear exchange near the beginning, one near the middle and one near the end. Use recognizable words, a shared reference or another event the editor can identify on both tracks. Note the approximate timing difference at each point.
If the difference is similar throughout, moving the whole track may be a useful first correction. Listen to the conversation afterward, since network delay and overlapping speech can make a single visual cue misleading.
If the difference grows, do not keep moving the entire track back and forth. Check the source file information and the import process. Confirm that sample-rate conversion was performed correctly and that no section was accidentally stretched or removed.
Keep corrections visible
Work in a saved project version and write down the regions you changed. If you make separate timing adjustments in several places, listen across each boundary for a jump in rhythm or a missing word.
Check the final export at the same three points. A correct timeline view is not enough if the export uses a different file or an earlier version of the project.
Preserve the original recordings so the timing decision can be revisited. When handing the project to another editor, describe whether you found a constant offset or changing drift. That short distinction gives them a much better starting point than a note saying only that the tracks were out of sync.
