hello
i need a diagram for a circuit that amplifies sound and speech
it is supposed to give out a constant output whatever the input is
(ex. if i speak in a low voice the circuit is supposed to increase the gain and give it as the output and if i speak in loud voice it is supposed to reduce the gain and give it as the output)
i looked it up and it is called a gain amplifier or a pre-amp circuit but i couldn't find what i was looking for
any help would be appreciated
thanks in advance
