NAS Overview
This page contains information for the Network Audio System (NAS), a network-transparent, client/server audio system originally developed at Network Computing Devices (NCD) by Jim Fulton, Greg Renda, and Dave Lemke that includes:
- sample server implementations
- VOXware/OSS (FreeBSD, Linux, SVR4.[02], UnixWare, Microsoft Windows using Cygwin)
- HPUX (HPPA, HP-UX 10.x, 11.x)
- Sun Sparc/Intel Solaris 2.x, AM79C30A Digital Subscriber Controller and Sparc 10 Dual Basic Rate ISDN Interface (SunOS 4.1.[23], Solaris 2.x)
- SGI Indigo (IRIX 5.x)
- an application programming interface library
- a variety of sample applications
The client software can also be used with several models of NCD X terminals as well as NCD's PCXware (an X server for PCs running Microsoft Windows).
Key features of the Network Audio System include:
- Device-independent audio over the network
- Lots of audio file and data formats
- Can store sounds in server for rapid replay
- Extensive mixing, separating, and manipulation of audio data
- Simultaneous use of audio devices by multiple applications
- Use by a growing number of ISVs
- Small size
- Free! No obnoxious licensing terms
Latest News
11/10/2007
NAS 1.9.1 (stable) is now available. This version adds some enhancements to aupanel, and reworks signal handling in the voxware server to avoid races, hangs and other issues seen with linux 2.6.21+ kernels.
6/21/2007
NAS now has an official project on Sourceforge. The Sourceforge NAS project page can be found at https://sourceforge.net/projects/nas .
The Subversion (SVN) repository has also been moved to the Sourceforge SVN server for NAS. The new SVN URL for current development is http://nas.svn.sourceforge.net/svnroot/nas/trunk. I have disabled the NAS SVN repository at radscan.com to avoid having to maintain/sync two repositories.
Per Øyvind Karlsen has setup a mediawiki page on Sourceforge as well. It can be accessed here. There isn't much there yet, but presumably stuff will be added as we go along. :)
NAS release 1.9 is also now available via the NAS Download page.
Any further public file releases (devel and stable) will be released via this mechanism. There is a big green button on the NAS Project page that will take you to the download page as well.
Current source packages that are available from the radscan.com website will continue to be available for at least 6 months (probably longer). After that, you'll have to get them via Sourceforge.
In time, this website (or the NAS portion of it anyway) will be migrated to the project web/wiki space on Sourceforge.
The nas mailing list will not be moved or changed in the forseeable future. The mailing list archives will also continue to be hosted here.
