I have noticed a motor whine recently that I don't remember hearing before. It only occurs at very low load levels, but it's loud enough that I was able to capture it on my phone. It reminds me of the whine you hear on your stereo when you turn the volume and gain up too high. It is most noticeable at the 1:20 mark if you don't want to hear turn signals for sound baselining. The linked file is aac which my phone played no problem .... Anyone else notice this noise ?
