Audio tracks in Ardour have a <dfn>mode</dfn> which affects how they behave
|
||
|
|
when recording:

|

|
|
<table class="dl">
|
||
|
|
<tr><th>Normal</th>
|
||
|
|
<td>Tracks in <dfn>normal mode</dfn> will record non-destructively—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—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>
|

|
|
<tr><th>Tape</th>
|
||
|
|
<td><dfn>Tape-mode</dfn> tracks do <strong>destructive</strong> recording:
|
||
|
|
all data is recorded to a single file and if a section of
|
||
|
|
existing data is overdub, 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 re-recording workflows, but is not
|
||
|
|
suggested for normal
|
||
|
|
use.</td></tr>

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.
