    • Viewable
      • samer.audio.FileSource2
  • All Implemented Interfaces:
    AudioSource

    public class FileSource2
extends Viewable
implements AudioSource
    An AudioSource that read from multiple audio files. Can read any format for which the appropriate JavaSound plug-in is installed on your system, eg WAV, AU, MP3, OGG. The implementation of AudioSource.reader() returns a Task which gets samples from the audio files, going through the play list one by one. An EOFException is thrown if an attempt is made to read beyond the end of the last file. FileSource2 is a Viewable called "playlist", and an Agent with commands next, view.
