Handling noise

By Apr.29, 2014

Handling noise occurs when a user brushes or knocks a recording device while recording is in progress.  There are two types of handling noises, rubbing type noises, as may occur as a device is brushed against clothing and more impulsive types of noise such as when a mic is dropped.

Here are is an example of handling noise.  The noises were recorded on an iphone and added to sounds taken from Freesound.

These type of sound can be highly disruptive, due to the proximity of the noise generating mechanism to the microphone diaphragm, these types of sounds can cause a significant reduction in signal to noise ratio.  It is our plan to design and implement a series of detection algorithms which can identify when these type of sounds may occur,  This can enable regions in sounds to be labeled automatically when this kind of problem occurs.
