<h3>Using Playlists for Parallel Processing</h3>
<p>
One of the uses of playlists is to apply multiple effects to the same audio
stream. For example, applying two different non-linear effects such as
distortion or compression to the same audio source (linear effects can be just
applied one after the other in the same track) can be done by creating a new
track, applying the original track's playlist, and then applying effects to
both tracks independently.
</p>
<p class="note">
The same result could be achieved by feeding the track to multiple busses
which then contain the processing, but this increases the overall latency,
complicates routing and uses more space in the Mixer window.
</p>
<h2>Using Playlists for "Takes"</h2>
<p>
Using Playlists for <dfn>takes</dfn> is a good solution when one needs the
ability to edit individual takes, and select between them.
</p>
<p>
Each time a new take is started, a new playlist should be created with <kbd
class="menu">p &gt; New</kbd>. Thus, later, any previous or later takes can be
selected as desired.
</p>
<p>
Creating a composite edit from multiple takes, can be achieved either:
</p>
<ul>
<li>by creating a new track to assemble the final version, and "cherry picking" from
the playlists in the original track by copying regions over as required</li>
<li>by recording each successive take on top of the others in "layers" and then
editing them using the layer tools.</li>
</ul>
<h2>Using Playlists for Multi-Language Productions</h2>
<p>
The same approach as for takes is useful when recording or editing content in
multiple versions, such as dubbed movie dialog in several languages: having
all versions on the same track allows to apply the same processing, making it
easy to switch language before exporting the session.
