Examples of javazoom.jl.player.AudioDevice

javazoom.jl.player.AudioDevice
The 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 
```
