Algorithm 1 Adaptive threshold computation

Require: sound signal of n values

Ensure: adaptive threshold value $Θ$

1:
$C_{a r r}$ ← Nb of crosses between S and $Θ$ , $Θ$ ranging from 0.01 to 0.5
2:
$C_{m a x} = max (C_{a r r})$
3:
$Θ_{m a x} = a r g m a x_{Θ} (C_{a r r})$
4:
if $C_{m a x} = = 0$ then
5:
return 0
6:
end if
7:
if elbow present in $C_{a r r}$ then
8:
return $Θ$ at the elbow
9:
end if
10:
if $max (C_{a r r}) > 2$ then
11:
return $min (Θ)$ s.t. $C_{a r r} < 2, Θ_{m a x} < Θ$
12:
else
13:
return lowest $Θ$ (0.01)
14:
end if
