Select a mark to inspect it, then use Seek to selection or Listen around mark. Adjust its timestamp or drag its selected handle. Click a note to add a finer mark. Timing between marks is interpolated. Manual corrections still need explicit review. The score uses printed spacing; the waveform uses recording seconds.

Edits stay here while you browse. Saving preserves the previous version. Changed audio or scores need fresh alignment. Fine timing requires listening and numeric adjustment; the waveform is not a 5ms measurement.
