Class LineSource

  • All Implemented Interfaces:
    AudioSource

    public class LineSource
extends VLine
implements AudioSource
    An AudioSource that reads from the sound card in real time. Uses a standard JavaSound TargetDataLine to get data. However, an alternative DataLine can be supplied instead. Audio format is determined by current environment--see VLine.

    Object is a Viewable, and is called "linein". Node is created in current context, ie with a parent determined by current Environment.
