Raw Normal View History

<p>
Audio tracks in Ardour have a <dfn>mode</dfn> which affects how they behave
when recording:
</p>
<table class="dl">
<tr><th>Normal</th>
<td>Tracks in <dfn>normal mode</dfn> will record non-destructively&mdash;new
data is written to new files, and when overdubbing, new regions will be
layered on top of existing ones. This is the recommended mode for most
workflows.
</td></tr>
<tr><th>Non-Layered</th>
<td>Tracks using <dfn>non-layered mode</dfn> will record
non-destructively&mdash;new data is written to new files, but when
overdubbing, the existing regions are trimmed so that there are no overlaps.
This does not affect the previously recorded audio data, and trimmed regions
can be expanded again at will. Non-layered mode can be very useful for spoken
word material, especially in combination with
<a href="@@pushpull-trimming">push/pull trimming</a>.
</td></tr>

<p>
The screenshot on the right shows the subtle difference between an overdub
in <dfn>normal mode</dfn> (upper track) and one in <dfn>non-layered mode</dfn>
(lower track). Both tracks were created using identical audio data.
</p>
<p>
The upper track shows a new region which has been <dfn>layered on
top</dfn> of the the existing (longer) region. It can be seen by the region
name strips.
</p>
<p>
The lower track has split the existing region in two, trimmed each new
region to create space for the new overdub, and inserted the overdub region
in between.

The switch between normal and non-layered modes is a global setting available
in the main toolbar.
