    1) The visualizer works on audio output, not input. So you'd need to try playing the sound while recording it. This would not be ideal on most devices as Android does not support low latency audio and would lag behind the recorded sound.

    2) Make sure that the btnStopRec_click does nothing until the btnRec_click sub has been run. Use a global variable.
