13 <td>Tracks using <dfn>non-layered mode</dfn> will record
14 non-destructively—new data is written to new files, but when
15 overdubbing, the existing regions are trimmed so that there are no overlaps.
16 This does not affect the previously recorded audio data, and trimmed regions
17 can be expanded again at will. Non-layered mode can be very useful for spoken

22 <td><dfn>Tape-mode</dfn> tracks do <strong>destructive</strong> recording:
23 all data is recorded to a single file and if a section of
24 existing data is overdub, the existing data is destroyed irrevocably—there is no
25 undo. Fixed crossfades are added at every punch in and out point. This mode
26 can be useful for certain kinds of re-recording workflows, but is not

41 (lower track). Both tracks were created using identical audio data.

45 top</dfn> of the the existing (longer) region. It can be seen by the region
