    diffTimeNanosLimit = diffTimeMillisLimit * millisToNanos;

    // Open the input line, the wanted buffer size is N times as big as the frame size
    inputLine.open(audioFormat, 4 * capturedFrameSizeInBytes);
    inputLineBufferSize = inputLine.getBufferSize();

    // Go to state idle

    // Start the capturing thread, it will block until startProcessing is called
    thread.start();
