Class com.sun.media.sound.AudioSynthesizer

Examples of com.sun.media.sound.AudioSynthesizer.openStream()

com.sun.media.sound.AudioSynthesizer.openStream()
Opens the synthesizer and renders audio into returned AudioInputStream.
An application opening a synthesizer explicitly with this call has to close the synthesizer by calling {@link #close}. This is necessary to release system resources and allow applications to exit cleanly.
Note that some synthesizers, once closed, cannot be reopened. Attempts to reopen such a synthesizer will always result in a MidiUnavailableException. @param targetFormat specifies the AudioFormatused in returned AudioInputStream. @param info a Map object containingproperties for additional configuration supported by synthesizer. If info is null then default settings are used. @throws MidiUnavailableException thrown if the synthesizer cannot beopened due to resource restrictions. @throws SecurityException thrown if the synthesizer cannot beopened due to security restrictions. @see #close @see #isOpen
