Audience was an American mobile voice and audio-processing company based in Mountain View, California, and was one of the 34 founding members of The Open Handset Alliance.

They specialized in improving voice clarity and noise suppression for a broad range of consumer products, including cellular phones, mobile devices and PCs.

Using the principles of CASA, Audience's earSmart processors act like a human cochlea and group different sounds, based on a diverse list of cues such as pitch, onset/offset time, spatial location and harmonicity.

In doing this, the microphones of a mobile device, together with Audience's proprietary "Fast Cochlea Transform" technology, can identify and group sounds which are classified as noise, remove or at least reduce them, and leave the remaining clear voice signal intact.
