Obtains a target data line that can be used for recording audio data in the format specified by the AudioFormat object.

Usage

From source file:org.snitko.app.record.SoundRecorder.java

public AudioInputStream record(long durationInSeconds) throws LineUnavailableException {
    Mixer.Info[] mixers = AudioSystem.getMixerInfo();
    for (Mixer.Info mixer : mixers) {
        System.out.printf("mixer name/desc/vendor/version: %s, %s, %s, %s\n", mixer.getName(),
                mixer.getDescription(), mixer.getVendor(), mixer.getVersion());
    }//from ww  w . ja  v a2  s . c  o m

    AudioFileFormat.Type[] types = AudioSystem.getAudioFileTypes();
    for (AudioFileFormat.Type type : types) {
        System.out.println("audio types are: " + type.toString());
    }

    AudioFormat audioFormat = getAudioFormat();
