yes, it's so simple! The only one non-zero sample represent an unitary
impulse which transform is a flat amplitude response and a linear phase
response. So i've a delay line.
i know that a simple delay line is the easiest way to add delay, but i use
a delay "filter" because i want to decompone it in its polyphase
components.
can i make another question? which is the difference between latence and
delay group? thank you
