Optimize audio amplifier for safe opening
I am trying to do a DIY amp but I need to know what frequencies to emphasize and what to try and filter out.
Perhaps some one with a bought amplifier has a manual that outlines the frequencies

I showed it to a friend who now knows what I want to do. He has a lot of gear
to do something like this.
His main hobby is recording birds and wildlife found in the city.
He has a parabolic microphone and showed me how he can filter noise so that
you can hear conversations in noisy traffic.
