Notes

This filter provides the amplitude level as a percentage value in floating point. This does not do any "slowing" of the data by averaging out peaks and troughs of short duration like a VU meter. Applications can also get this data on the frame as meta.media.audio_level.<N> where <N> is the channel number starting with 0.
