In order to accomplish this, the SourceDataLine object must know about the format of the audio data, including the sample rate, the number of channels, the number of bits per sample, etc. That information was provided to the SourceDataLine object by way of the DataLine.Info object in Listing 10.
javax.sound.sampled.SourceDataLine for playing back audio in specified format to the audio device. Basic sound generation. In simplest way, sound can be visualized in format of sine wave of different amplitudes. We can use this simplest idea to create a basic sound in Java.
My card for example, cannot play 8 bit 8khz u-law audio. One option that was mentioned was to convert the audio format that you read from the file to an audio format that can be played. See my code below, it converts the format to PCM_SIGNED that can be played by most cards. Andrew's Clip idea is a good one too, see the second code example.
*/ Sound in Java 2 jonkv@ida Early Java: Verysimple sound API Can play, loop or stop audio clips Only handles.AU audio files – 8-bit sound, mono , 8 kHz Can only be used in applets (in web pages), not in applications 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. A JavaSound Mixer is a logical container object, or grouping mechanism, for Lines (SourceDataLine, TargetDataLine, or Port). Typically, a JavaSound Mixer corresponds to a specific audio hardware component or device (for example, a D to A circuitry for playback of audio data in our figures). JavaSound inheritance hierarchy speakers - library book java program . 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.

@Florian thank you for this example. And what means if int n=soundLine.write(buffer, 0, bufferSize); n returns 0 value after 2 first writing? – user390525 Apr 11 '17 at 20:36 @user390525, per the spec of SourceDataLine.write(), it can only return less than the specified buffer size in case of an error (malformed parameters) or if the SourceDataLine got stopped, flushed, or closed.
In my present naive demodulation strategy, I simple scroll through the sample data at half the width of a single character, looking for bit patterns to change. When receiving a random signal off-air, this probably would not be adequate and a better strategy would need to be devised to be sure demodulation began at the start of a new character. jsresources-examples / src / main / java / org / jsresources / audioloop / AudioLoop.java / Jump to Code definitions AudioLoop Class start Method run Method main Method printUsageAndExit Method out … A JavaSound Mixer is a logical container object, or grouping mechanism, for Lines (SourceDataLine, TargetDataLine, or Port).

EVALUATION see bug #4288683: "Clip does not throw exception if data cannot be loaded." due to a known limitation in the engine, we cannot have more than 1M of samples per buffer. this is the same limitation as the 1M limit on clip size, and will be fixed when we next merge in beatnik's new code. the limit is 1 megabyte of samples, not 1 megabyte.

The JDK has a audio integration as standard – but for some reason it is ill used and poorly documented. When I started coding Sonic Field it was silent. Yes, it could synthesis audio signals and processes recordings; however, playing an arbitrary piece of audio with javax.sound was beyond me and even Google did not […] 2013-07-08 · Java beep sound exampleThere are different ways to generate a beep sound in java.
