SourceDataLine (Java Platform SE 7 ) All Superinterfaces: AutoCloseable, DataLine, Line. public interface SourceDataLine extends DataLine. A source data line is a data line to which data may be written. It acts as a source to its mixer. An application writes audio bytes to a source data line, which handles the buffering of the bytes and delivers

The SourceDataLine interface provides a method for writing audio data to the data line's buffer. Applications that play or mix audio should write data to the source data line quickly enough to keep the buffer from underflowing (emptying), which could cause discontinuities in the audio that are perceived as clicks.

Java-recording from mixer (2) This filter will sample at 0.06 of the sample rate regardless of what that is. So it will work just the same for 192000 samples per second, giving a cut of rate of 192000 * 0.06 = 11.5kHz. To calculate the first filtered value we imagine our data as shown below. My card for example, cannot play 8 bit 8khz u-law audio.

This is not only a capability of synthesizers, but also of Java.

NullPointerException is an example of typical and acceptable run time exception for such cases. A source data line is a data line to which data may be written.

if (thread != null) { line.drain(); } line.stop(); line.close(); line = null; thread = null; } private SourceDataLine getSourceDataLineForPlayback() { SourceDataLine line; final DataLine.Info info = new DataLine.Info(SourceDataLine.class, format); if (!AudioSystem.isLineSupported(info)) { return null; } // get and open the source data line for playback.

Also, writing data byte by byte to the SourceDataLine is very inefficient (the buffer size is set in the open() method, not in write()), as a rule of thumb I'd always write one full buffer size to the SourceDataLine. After setting up the SourceDataLine, use this code:

getSourceDataLine (af); line. open (af, Note.SAMPLE_RATE); line. start (); for (Note n : Note.values()) { play(line, n, 500); play(line, Note.REST, 10); line. drain (); line.

The following examples show how to use javax.sound.sampled.SourceDataLine. These examples are extracted from open source projects. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example.

An application writes audio bytes to a source data line, which handles the … In this case, a SourceDataLine is more appropriate than a Clip. Another example of sound that can't be known in advance occurs when you synthesize or manipulate the sound data interactively in response to the user's input. For example, imagine a game that gives aural feedback by "morphing" from one sound to another as the user moves the mouse. public static SourceDataLine getLine(AudioFormat audioFormat) throws LineUnavailableException { DataLine.Info info = new DataLine.Info(SourceDataLine.class, audioFormat); SourceDataLine res = (SourceDataLine) AudioSystem.getLine(info); res.open(audioFormat); return res; } javax.sound.sampled.SourceDataLine for playing back audio in specified format to the audio device.
