Examples of EDLChunk

com.meapsoft.EDLChunk
Representation of an EDLFile Chunk Note that EDLChunk extends FeatChunk so that it can inherit the feature stuff from FeatChunk. This is really only to associate each EDL chunk with a set of features for visualization purposes (i.e. with ImagePanel, to see how the composers rearrange things) since the features associated with chunks in EDLs are basically irrelevant. @author Ron Weiss (ronw@ee.columbia.edu)

    {
      //your current features chunk
      FeatChunk ch = (FeatChunk)c.next();


      //make a new EDL chunk from the current features chunk
      EDLChunk original = new EDLChunk(ch, currTime);
      //we're going to make one more chunk for the backwards part
      EDLChunk backwards = new EDLChunk(ch, currTime+ch.length);
      
      //tell the 2nd chunk to add the reverse command so that
      //when the synthsizer sees this chunk it will render the audio
      //in reverse
      backwards.commands.add("reverse");
