An automated system and method are disclosed for the removal of background noise from audio signals. The system takes input of multiple recordings of the same event and gives an output of a single audio stream. This audio stream emphasizes the common components of the inputs and attenuates components that are not perceived in all the recordings. The method removes constant background noise and shorter impulse noises effectively through , audio preprocessing, noise detection and attenuation, and final signal synthesis. Any video or audio editing software could use this method to create clearer audio signals with less background noise.
