"4Front Technologies is proud to announce the release of the source code to Open Sound System v4.0 under the BSD license for FreeBSD and other BSD compliant operating systems. OSS is a cross platform API that provides drivers for most consumer and professional audio devices for UNIX and POSIX based operating systems, including Linux. Owing to its open architecture, applications developed on one supporting operating system platform can be easily recompiled on any other platform. Open Sound System is also available for Linux under the GPLv2 license and OpenSolaris under the CDDL license. It is also available for commercial and proprietary operating systems under the 4Front commercial license."
