Sound Analyzer

I am looking for a front end developer to develop an audio analyzer for most common web browsers. The web browser should have waveforms to display the intensity of the sound around the mic. To also improve the experience it should also display the approximate intensity and compare it to common noises heard in daily life. For example, the program should spike the waveform when a full volume music video plays near the mic and then list it’s db value while also listing that an average person speaks at 60 dB. Potential common noises that I want to be listed are average conversation, scream, crying, sobbing, laughing, whispering, car honks, emergency siren.
