pub const DROP_BAND_GATE: Decibels;Expand description
A strike whose RMS in the band of the line, over the 20 ms after the
onset, lies more than this below the loudest QUIET_FRAME of that
band in the stem is no candidate.
Checked against an independent IF on real stems, the drops of a line’s own low notes read 3 to 12 dB below the loudest passage of the band. Quiet falls under a louder line in the band, and a fall in a noise floor, read 22 to 33 dB below it.
