GStreamer 1.0 Good Plugins: level Return RMS = [-699.9999998436322, -699.9999998436322]

[Luis de Bethencourt]

In my machine it returns:
[-45.52592812710999, -45.47488150930283]
[-47.53910343727122, -47.766107828050835]
[-48.14226846092638, -48.37797057538709]

I don't understand the question, why what?
