2 Audio tracks in Ardour have a <dfn>mode</dfn> which affects how they behave
7 <td>Tracks in <dfn>normal mode</dfn> will record non-destructively—new
8 data is written to new files, and when overdubbing, new regions will be
9 layered on top of existing ones. This is the recommended mode for most
12 <tr><th>Non-Layered</th>
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
18 word material, especially in combination with

31 The screenshot on the right shows the subtle difference between an overdub
32 in <dfn>normal mode</dfn> (upper track) and one in <dfn>non-layered mode</dfn>
33 (lower track). Both tracks were created using identical audio data.
36 The upper track shows a new region which has been <dfn>layered on
37 top</dfn> of the the existing (longer) region. It can be seen by the region
41 The lower track has split the existing region in two, trimmed each new
42 region to create space for the new overdub, and inserted the overdub region
47 The switch between normal and non-layered modes is a global setting available
