I got your part but i thought using simply lm386 omiting the above circuit then using a second order speech filter(that pass 300 to 3400hz)...will this make any difference than your solution
If i use this second order speech filter(pass 300 to 3400 hz) after lm386..will this work??
but the only problem with this op-amp is supply of +9and -9V so i am also searching for the alternative of this opamp if the above solution works
using lm386, i am getting output biased about 2.7 rather than about Vcc/2(=2.5V)..I need output biased across exact 2.5V..what can be the possible problems or solutions
if i use lm386 followed by a second order speech filter....will the problem be solved and un-necessary noise will be rejected/reduced

will this work for reducing hiss???
I am using lm386 for signal amplification recievied from microphone and then send them to analog pin of arduino..do i need a speech filter circuit also between lm386 and arduino or lm386 would limit the frequency response to 300-3400hz (the speech audio spectrum range)??....
{ basically i am...
