I listen to some shows while doing other things, one talk show has the talk voice really low and the ads are VERY loud. Is there an app that will set the max sound such that I can turn the volume up and hear the talk without having the ads blast the speakers out? I know in iOS you have APIs that that can control sound, but I'm wondering if there's one for OSX. It would be kinda like a sound safeguard that would probably just monitor the sound level and drop the volume if it goes too high, then restore to normal after a set period of time. I haven't written any OSX apps, just iOS, so I don't know much about it and would rather just download one.
