<h5>About flac tool</h5>
|

<p>The flac tool is the tool created by the FLAC project to transcode to/from FLAC and to manipulate metadata in FLAC files. One advantage it has over other tools used to transcode into FLAC is the capability of embedding foreign metadata (such as BWF metadata). This means that it is possible to compress a BWF file into FLAC and maintain the ability to transcode back into an identical BWF, metadata and all. For a more detailed explanation, see <a href="http://dericed.com/2013/flac-in-the-archives/" target="_blank">Dave Rice's article</a> on the topic, from which the following commands are adapted.</p>
