To be sure you output the data that was read you need to use: Stream.RENDERING_BUFFER.write(Stream.READ_BUFFER, 0, numRead); The reason you are reading nothing is because you have not started the TargetDataLine, How can I find out which soundcard driver is used?5.3. Say you have the following "sound" data at 8000, and you want to convert it to 16000. 1 3 1 3 1 3 1 3 (@ 8000) becomes 1 ? 3 Why does AudioInputStream.getFrameLength() return -1?10.10. http://electrictricycle.net/cannot-be/cannot-be-cast-to-javax-jms-connectionfactory.html
A useful definition would be the following:isActive() returns true if the line is in started state, i.e. Es behandelt genau das gleiche Thema, wenn ich es geschafft habe, werde ich es hier posten :toll: Spacerat Ich nehme mal an, dass du beide gepostete Programmabschnitte auch verwendest, aber Do multiple Clip instances that are looped stay in sync?6.5.

Is it possible to insert recorded audio data into an existing file?7.20. I doubt you need to worry about anything more complex than the linear interpolation I discussed above.

Are there native implementations of codecs that are compatible with the framing format used by the Java Sound GSM codec?12.4. Like that you treat buffers of small size and feed them successively into the audio device. There is too much buffering in the data path (also in the audio hardware), so calculating the position is always only an estimation.If you try to measure the precision of DataLine.getMicrosecondPosition() So... // Clip c= AudioSystem.getClip(mixerInfo); OLD WAY DataLine.Info info = new DataLine.Info(Clip.class, audioFormat); Clip c = (Clip)m.getLine(info);But a note about your audioFormat...
Maybe if you gave us a little overview of what you are actually trying to accomplish we could give you better directions. -- Knute Johnson email s/nospam/knute/ Knute Johnson, Aug How can I get more than one TargetDataLine?1.3.3. if you do not reply to this email, you will not be able to view certain areas of the forum or certain images... As a workaround, you can close unused clips and open them once they are needed again.

Java Sound does not provide a way to query this possibility or to switch it on or off. And by 'code' I mean a specific form, an SSCCE. I am not sure it will help you, but here is a small sound based tool I wrote to plot The real-time clock of the computer can be synchronized to atomic clocks by using some means of synchronization. Why do I get lines from the "Java Sound Audio Engine" in the JDK 1.5.0 though the "Direct Audio Device" mixers are available, too?4.1.What are all these mixers?There are several implementations

In general, it is recommended to use isActive(), since it is specified less ambigously and it is implemented consistently. Which input formats can I use for the mp3 encoder?12.2.8.

How can I find out the current playback or recording position?1.1.15. So mixing of multiple playback lines is only available if either the soundcard hardware or the device driver are capable of mixing. Why are there no Port instances of certain predefined types (like Port.Info.MICROPHONE or Port.Info.COMPACT_DISC) on Linux?15. this contact form When your soundcard does not support -law directly, the TargetDataLine won't either.The way to go is to open a TargetDataLine in pcm format and route it through a format converter.

In any case the SPEAKER port controls for a given sound card will work with any any source mixer.
