Given
the number n of F
tial amplitude to 36.8% is
With an initial amplitude of 0xFF the total time t
to reach zero amplitude in the 8 Bit - AMAS is n = 193 F
ment
With an initial amplitude lower than 0xFF the gong sound
duration is shorter.
That means that

mula.
To sum up it can be said that the total duration of the gong
sound depends on F
ting of the Gong Duration Factor GDF and the setting of the
initial amplitude AMAS.
