public interface AudioDevice
AudioDevice
interface provides an abstraction for
a device capable of sounding audio samples. Samples are written to
the device wia the write() method. The device assumes
that these samples are signed 16-bit samples taken at the output frequency
of the decoder. If the decoder outputs more than one channel, the samples for
each channel are assumed to appear consecutively, with the lower numbered
channels preceeding higher-numbered channels. E.g. if there are two
channels, the samples will appear in this order:
l0, r0, l1, r1, l2, r2...
where
lx indicates the xth sample on channel 0
rx indicates the xth sample on channel 1
Since: 0.0.8
Method Summary | |
---|---|
void | close()
Closes this audio device. |
void | flush()
Blocks until all audio samples previously written to this audio device have
been heard. |
int | getPosition()
Retrieves the current playback position in milliseconds. |
boolean | isOpen()
Retrieves the open state of this audio device.
|
void | open(Decoder decoder)
Prepares the AudioDevice for playback of audio samples. |
void | write(short[] samples, int offs, int len)
Writes a number of samples to this AudioDevice .

write
or flush
operation should be unblocked by this method.Returns: true
if this audio device is open and playing
audio samples, or false
otherwise.
Parameters: decoder The decoder that will be providing the audio samples. If the audio device is already open, this method returns silently.
AudioDevice
.
Parameters: samples The array of signed 16-bit samples to write to the audio device. offs The offset of the first sample. len The number of samples to write. This method may return prior to the samples actually being played by the audio device.
