pub const RISE_PERIODS: f64 = 2.0;Expand description
The span, in periods of the note, of the band envelope average that tells a strike found again from a strike of its own.
A search that starts where the previous one ended, inside the rise of the strike read last, is lowest at its first sample. A new strike dips first. A second harmonic in the band beats with the fundamental, and the beat dips a 10 ms average by up to 12 dB. On 456 generated sweeps with the border 20 ms before to 70 ms into the strike, a 10 ms average read a second drop 21 times. One period read 5, 1.5 periods 1 and two periods none. Over three periods, 90 runs of 808 hits struck every 115 ms lost 2 of their drops.
