pub const NOTE_LINE_LOSS: Decibels;Expand description
A fit on the note line counts when the note line keeps the fall: its RMS envelope over the fall lies at most this far below the band’s.
Over the fall of four true drops on real stems the note line lay 2.2 to 3.8 dB below the band, and generated sweeps 2.2 to 3.6 dB. A tone an octave above a real note, with the note’s own tone entering 80 ms after the strike, lay 10.8 dB below: the note line held the upper tone 18 dB down, and its line fell from it to the lower one as that entered. Generated tones of that shape lay 4.8 to 7.6 dB below, so the ones under this edge still read as drops. The margins are thin: the true drops lie 2.2 dB under the edge at most, and the false tones of the tests 0.6 and 1.3 dB over it.
