Under less than ideal conditions, even the best microphone embedded in a laptop or monitor does a poor job of capturing sound. An array of microphones can do a better job of isolating a sound source and rejecting ambient noise and reverberation. This paper provides information about the advantages microphone arrays can offer and about the support for microphone arrays provided in the Windows Vista operating system.

If you are a laptop or monitor manufacturer or designer working to provide better sound capturing quality by integrating microphone arrays with Universal Audio Architecture (UAA)-compliant High Definition (HD) Audio-based devices, or if you are a hardware manufacturer designing Windows-based external USB Audio microphone arrays, this paper provides design guidelines for building microphone arrays that will work well with Windows Vista.

Included in this white paper:

• Microphone Arrays as PC Product Solutions: An Overview

• Windows Vista and Microphone Array Solutions

• About Microphone Arrays

• Microphone Array Characteristics

• Supported Microphone Array Geometries

• Design Considerations

• Next Steps
