<div class="textblock"><p>Abstract base class for sound file encoding. </p>
<p>This class allows users to write audio file formats not natively supported by SFML, and thus extend the set of supported writable audio formats.</p>
<p>A valid sound file writer must override the open and write functions, as well as providing a static check function; the latter is used by SFML to find a suitable writer for a given filename.</p>
<p>To register a new writer, use the <a class="el" href="classsf_1_1SoundFileFactory.html#abb6e082ea3fedf22c8648113d1be5755" title="Register a new writer. ">sf::SoundFileFactory::registerWriter</a> template function.</p>
