noise gate

Hi,

I need help with noise gate implementation.I have input wav file as byte array on which I have to implement noise gate.I have already done fft and calculated amplitude.I'm not sure what next should I do.I mean, I know basic procedure, but do I compare amplitude with threshold or something else? Is output = input * gate?
Thanks in advance. Start a New Thread

Thank you very much :), just one more question, to be sure : i compare
amplitude with the threshold an depending on that i release(or not) the
INPUT signal, directly?
Thanks in advance Start a New Thread
