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).
