NAME

Audio::DSS - Extract meta data from Digital Speech Standard (DSS) files

SYNOPSIS

  use Audio::DSS;
  my $dss = new Audio::DSS;
  $dss->{file} = 'dss_is_cool.dss';
  $dss->getDSSMetaData();

  or

  my $dss = new Audio::DSS(file=>'dss_is_cool.dss');;

  print $dss->{file};  
  print $dss->{create_date};  
  print $dss->{complete_date};  
  print $dss->{length};  
  print $dss->{comments};  

  There is a utility program to dump dss for you:
  dumpdss.pl /somepath/*.dss

  the file eg/dss_is_cool.dss can be used for testing:
  eg/dumpdss.pl eg/dss_is_cool.dss 
  file|create_date|complete_date|length|comments

  returns: 

  eg/dss_is_cool.dss|2004-08-17 17:33:02|2004-08-17 17:33:04|000002|DSS File comments are sadly limited to 100 characters, and this comment uses every one of them, see?|

DESCRIPTION

Extract the meta information from a Digital Speech Standard (DSS) file. DSS is a compact file format used for recording voice. It is used in Olympus Digital Voice Recorders.

To be precise, I assume it is used all over, but I _know_ that it is used in the Olympus DS-330 Digital Voice Recorder.

My voice recorder supports five different folders, and many different tracks in each folder. The interface software then sucks my recordings from the voice recorder onto my iBook, putting clips into individual dss files in one of five different directories.

The DSS header includes the time a track was created, when it was last edited, the total time, and up to 100 characters of comments. The key use case for this module is to pull time stamps then use the as yet unwritten and not really named 'Geo::Track::Interpolate' to syncronize DSS files with GPS track logs based on the time stamps.

Huh? Time is the universal foreign key! If you know what time something occurred then you can syncronize it with your GPS track log. Digital photos, voice records, heart rate monitoring, temperature, random stuff, etc.

Double huh? Syncronizing 'media' (Schuyler thinks these are all media, and I get wierded out by that language so put it in scare quotes) with position, or 'geocoding the media' is the key component of Quantitative Psychogeography. This is the quantitative study of spaces and our relationships with those spaces. Among other things.

As an aside, or intercalery, how much POD do I need to write for this module before my code to pod ratio exceeds all known limits?

EXPORT

None by default.

You should 'probably' think about using the GPX format if you want to share these tracks with other people.
