MagnitudeToDecibel Incorrect Scaling Constant

[daniel-deychakiwsky]

Its my understanding that when converting to decibel, the scaling constant should be 20.0 for magnitude mel/specgrams and 10.0 for power mel/specgrams. It seems the Kapre implementation anticipates a magnitude mel/specgram but scales it as if it is a power mel/sepcgram. Notice that Librosa's implementation, the power_to_db function, applies a 10.0 scaling factor but anticipates a power mel/specgram. Of course, this is a difference of a scaling but thought I'd mention it here. Any thoughts on that?
