Device Configuration for Skype Long-Range Speakerphone and TV Applications

By: Evan Ragsdale

Abstract: The MAX9860 audio voice codec provides an ideal solution for Skype® long-range audio-capture applications and enables high-quality voice transmission. Target applications include Skype for TV, set-top boxes, and speakerphones. By providing a flexible range of programmable gain settings and accepting sample rates up to 48kHz, the MAX9860 amplifies analog microphone signals and converts them to digital audio with performance in mind. In addition, the MAX9860's two microphone inputs allow the application to record from a two-microphone or four-microphone array using a beamforming algorithm for directional sensitivity and noise cancellation.
