JavaTM Sound Enhancements in
JDKTM 5.0
The following enhancements took effect at JDK 5.0.
- Ports are available on all platforms (RFE 4782900).
- MIDI device i/o is available on all platforms (RFE's 4812168,
4782924).
- Optimized direct audio access is implemented on all platforms
(RFEs 4908240 and 4908879). It is enabled by default on systems
which offer native mixing (i.e. Linux ALSA with hardware mixing,
Solaris Mixer enabled, Windows DirectSound).
- The new real-time Sequencer works with all MIDI devices and
allows unlimited Transmitters (RFE 4773012).
- The
sound.properties configuration file allows
choice of default devices (RFE 4776511). For details, see
MidiSystem and AudioSystem for
details.
- MidiDevices can query connected Receivers and Transmitters (RFE
4931387, methods MidiDevice.getReceiver and
MidiDevice.getTransmitter).
AudioFormat, AudioFileFormat, and
MidiFileFormat now have properties that allow further
description and qualification of the format (RFEs 4925767 and
4666845).- A set of ease-of-use methods allow easier retrieval of lines
from AudioSystem (RFE 4896221).
- The Sequencer interface is extended with loop methods, for
seamless looping of specific portions of a MIDI sequence (RFE
4204105).
- Java Sound no longer prevents the VM from exiting (bug
4735740).
