pub const GAP_DIP_DB: Decibels;Expand description
A gap of the track whose full-band RMS, over 10 ms, falls this far below the 20 ms before or after it is not bridged.
The dip breaks the sound, and the glide search reads the runs apart. So
does a gap that falls more than ACTIVE_GATE_DB below the loudest
frame of the stem.
