This FREE iPhone app lowers the volume or stops the music from the ipod when a loud/sudden noise happens nearby. It helps the user to be aware of the surroundings while comfortably listening to music.
It uses the built in microphone or the headphones microphone to assess the environment and control the playback of the music.

This is the first of a series of iPhone apps using Base 10 Labs’ iOS Audio Processing SDK framework
