Class StreamSource

  • java.lang.Object
    • samer.audio.StreamSource
  • All Implemented Interfaces:
    AudioSource

    public class StreamSource
extends java.lang.Object
implements AudioSource
    An AudioSource that read from an input stream. 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. If the loop flag is true, then samples are returned indefinitely by looping through the playlist; otherwise, an EOFException is thrown if an attempt is made to read beyond the end of the last file. Properties read from current environment:
    current
    Current file (String)
    loop
    Loop playlist? (Boolean) [true]
