Audio tracks in Ardour have a <dfn>mode</dfn> which affects how they behave
|
|
when recording:
|
|
</p>
|
|
<table class="dl">
|
|
<tr><th>Layered</th>
|
|
<td>Tracks in <dfn>layered 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>Sound on Sound</th>
|
|
<td>Tracks using <dfn>sound-on-sound mode</dfn> will record
|
|
non-destructively — new data is written to new files, but when
|
|
overdubbing, new regions will be layered on top of existing ones in non-opaque
|
|
mode which means both existing and new material will be played back after
|
|
the recording is over. This is convenient for a variety of use cases, such as
|
|
adding MIDI Control Change events on top of recorded live performance.
|
|
</td></tr>
|
|
</table>
|
|
|
|
<p>
|
|
Results of recording in layered and non-layered modes are visually the same.
|
|
However, with the sound-on-sound mode lower layers are visible under upper
|
|
layers, because in that case new regions with overdubs are created with
|
|
disabled <em>Opaque</em> setting.

To illustrate the difference, here is the screenshot of the same tracks, but
|
|
this time — in <em>Stacked</em> track mode (rather than
|
|
<em>Overlaid</em> as on the screenshot above).

|
The overdub is an opaque region on top of the original content for the
|
|
<em>Layered</em> mode. For the <em>Non-Layered</em> mode, it completely
|
|
replaces the matching part of the original content. And for the
|
|
<em>Sound on Sound</em> mode, it's a transparent region on top of the original
|
|
content.

|
|
The switch between layered, non-layered, and sound-on-sound modes is a global
|
|
setting available in the main toolbar right below the buttons enabling
|
|
Punch In and Punch Out.
