A 1000-byte block (if 4 bytes per frame) would theoretically have 1/1764 sec accuracy for an audio format with 44100 fps, 16-bit encoding, stereo. The accuracy will be regulated by the size of the buffer blocks. It is possible to directly feed data buffer blocks to multiple lines from a single source. Now, check whether the desired speakers are set as the default device. In the ‘Sound’ window that pops up, navigate to the ‘Playback’ tab. ![]() In addition to this, one has access to the individual bytes as they pass through the lines. To output audio to multiple devices, right-click on the ‘Speaker’ icon in the ‘System Tray’ and then select ‘Sounds’ from the menu. The first two lines in the list are emulators, and the third. Furthermore, the degree of accuracy with which operations are applied to the lines is controllable. The following example shows the devices command and its output. ![]() Some mixers facilitate this behavior with their synchronize method, which lets you apply operations such as open, close, start, and stop to a group of data lines using a single command, instead of having to control each line individually. If you're playing back multiple tracks of audio simultaneously, you probably want to have them all start and stop at exactly the same time. Java provides classes for incoming and outgoing lines: TargetDataLine, SourceDataLine.įrom the Sound Trail / Playing Back Audio
