something link this in the run method of the Capture class?: 

       	// !!!!!!
          	// try to find highest supported sampling rate
            if (!AudioSystem.isLineSupported(info)) {
                int samplingRate = 44100;
                AudioFormat format = new AudioFormat(samplingRate, samplingRateFormat, numberChannels, true, false);
                info = new DataLine.Info(TargetDataLine.class,format);
