libaudio2 1.7-3ubuntu3.2 (amd64 binary) in ubuntu dapper

 The Network Audio System was developed by NCD for playing, recording, and
 manipulating audio data over a network. Like the X Window System, it uses
 the client/server model to separate applications from the specific drivers
 that control audio input and output devices.
 .
 This package contains the nas library (libaudio), needed for both remote
 and local output.
