Project Overview

• Modern active loudspeaker system – Intended for consumers– Replaces audio receiver/passive loudspeaker

combination

• Digital manipulation of sound field– User controlled direction– Allows for non-ideal placement in a room

Project-Specific Success Criteria

1. An ability to receive and act upon command from an IR remote.

2. An ability to delay-steer the wave-front of a loudspeaker array (up/down, left/right).

3. An ability to amplitude-shade the wave-front of a loudspeaker array (adjust effective array length).

4. An ability to perform (third-octave) amplitude equalization.

5. An ability to control loudspeaker settings thorough a user interface.
