<dd>Tracks using this mode do <strong>destructive</strong> recording: all data is recorded to a single file and if you overdub a section of existing data, the existing data is destroyed (irrevocably - there is no undo). Fixed crossfades are added at every punch in and out point. This mode can be useful for certain kinds of dubbing workflows, but it not suggested for normal use.</dd>

<p>The screenshot below shows a subtle difference between results of an overdub in normal mode (upper track) and non-layered mode (lower track). Both tracks were created using identical audio data. The upper track shows an overdub (the middle shorter region) in normal mode. In normal mode Ardour created a new region which if you look carefully has been layered on top of the the existing (longer) region. The lower track is in non-layered mode, and rather than overlay the overdub region, it split the existing region and inserted the new overdub region in between. </p>
