[sdiy] More on Flanging...

[harry]

The trick to great flanging IS (imho) matched audio paths... and
delay of both paths. Digital units delay only ONE path... they can
come arbitrarily close to being 'in-phase'... but never make it.  If you
delay one path even one millisecond... the second delay can come right
up to it !
