![]() If a user would like to switch between multiple Bluetooth headsets, then they need to switch the active bluetooth headset from the system Bluetooth settings.In the event of a failure to connecting audio to a bluetooth headset, the library will revert the selected audio device (this is usually the Earpiece on a phone).Other connected headsets are not stored by the library at this moment.The library will accurately display the up to date active bluetooth headset within the AudioSwitch availableAudioDevices and selectedAudioDevice functions.Multiple connected bluetooth headsets are supported. And because the main method is blocked by method call AudioSystem.write(), closing the target data line will continues the main method which exits the program.Note: The stop() function will call deactivate() before closing AudioSwitch resources. Second thread (the stopper thread): waits for a specified duration before closing the target data line.First thread (main thread): captures and records sound.wav format.You can change the record duration by modifying value of the constant RECORD_TIME at the beginning of the class.Notice that there are two threads spawn in this program: mp3 format, but unfortunately the Java Sound API only supports the. wav format under E:/Test/RecordAudio.wav (so make sure you created the parent directory first). If (!AudioSystem.isLineSupported(info)) This console-based program will record sound from the microphone for 60 seconds then saves the recorded sound into a file in. checks if system supports the data line * Captures the sound and record into a WAV fileĭataLine.Info info = new DataLine.Info(TargetDataLine.class, format) the line from which audio data is capturedĪudioFormat format = new AudioFormat(sampleRate, sampleSizeInBits, Static final long RECORD_TIME = 60000 // 1 minuteįile wavFile = new File("E:/Test/RecordAudio.wav") ĪudioFileFormat.Type fileType = * A sample program is to demonstrate how to record sound in Java Here is the source code of a sample program which follows the steps above: import .* Stop and close the target data line to end capturing and recording.Note that this method blocks the current thread until the target data line is closed. Write(AudioInputStream, AudioFileFormat.Type, File) Record the captured sound into a WAV file using the following method of the class AudioSystem:.Create an AudioInputStream object to read data from the target data line.Open and start the target data line to begin capturing audio data.Obtain a TargetDataLine object which represents an input data line from which audio data can be captured, using the method getLineInfo(DataLine.Info) of the AudioSystem class. ![]()
