AudioRegent is a command-line Python script currently being used by the University of Alabama Libraries’ Digital Services to create web-deliverable MP3s from regions within archival audio files. In conjunction with a small-footprint XML file called SimpleADL and SoX, an open-source command-line audio editor, AudioRegent batch processes archival audio files, allowing for one or many user-defined regions, particular to each audio file, to be extracted with additional audio processing in a transparent manner that leaves the archival audio file unaltered. Doing so has alleviated many of the tensions of cumbersome workflows, complicated documentation, preservation concerns, and reliance on expensive closed-source GUI audio applications. - source: http://journal.code4lib.org/articles/2882
AudioRegent's default setup file, AudioRegent.xml, should be set as such:
<?xml version="1.0"?> <AudioRegentSetup> <outputType default="ogg">wav</outputType> <SoxOptions default="gain -n -3">gain -n -3 channels 1</SoxOptions> <comment default=""></comment> <delete_outWavs default="true">true</delete_outWavs> <timestampLogFiles default="false">false</timestampLogFiles> </AudioRegentSetup>
The XML parsing module used by AudioRegent will break on non-UTF-8 encoded SimpleADL XML files if any diacritic characters exist.
- To remedy this SimpleADL files should be encoded as UTF-8 files.
