Week 4 EOC: new phone app

Every time i watch a video that someone recorded on their phone, especially one from a concert, I cringe because the audio is terrible. Of course its terrible because i was recorded on a tiny little microphone that has never been updated.  When was the last time you saw new microphone technology go into your droid or iPhone, huh? You never hear it because they don't do it. All the talk is about the new camera and what it can do. Ok, so there was my rant and now for my app to solve this problem.  You cant fix the microphone that was installed by the manufacturer but we can change audio as it records. This new app will do two main "fixes." the first will be to atennuate the high levels down by -15dB this takes away the ear punching concert sound that sounds so cracked when recorded on a tiny mic. The second step is to get the mix sound that you are actually hearing while recording video and getting the same results when played back. This is done via an algorithm written into the app that will adjust for the bias of the microphones pick-up across the spectral range. Basically it will notch out frequencies and boost the lower mids to bring back what you thought was lost recording into such a tiny mic. I looked through the internet for an app like this already out there, and there is none. The closest thing i saw was an in-ear company that will pad loud noises down to a normal level but leave in the quality of the sound being heard without the plugs.
