Open Sound System(OSS)為首個試圖對 UNIX 數字音頻信號體系結構進行規範化整合的項目。
它是一系列的驅動程式,為所有主要的 UNIX 平台體系提供規範化的 API 程式調用編程介面。
Open Sound System (OSS) is the first attempt in unifying
the digital audio architecture for UNIX.OSS is a set of
device drivers that provide a uniform API across all the
major UNIX architectures. It supports Sound Blaster or
Windows Sound System compatible sound cards which can be
plugged into any UNIX workstation supporting the ISA or
PCI bus architecture. OSS also supports workstations
with on-board digital audio hardware.
Traditionally, each UNIX vendor has provided their own
API for processing digital audio. This meant that
applications written to a particular UNIX audio API
had to be re-written or ported, with possible loss of
functionality, to another version of UNIX. Applications
written to the OSS API, need to be designed once and
then simply re-compiled on any supported UNIX
architecture. OSS is source code compatible across all
the platforms.
Most UNIX workstations, thus far, have only
provided support for digital audio sampling and
playback (business audio). OSS brings the world of
MIDI and electronic music to the workstation
environment. With the advent of streaming audio,
speech recognition/generation, computer telephony,
Java and other multimedia technologies,
applications on UNIX can now provide the same audio
capabilities as those found on Windows NT, OS/2,
Windows 95 and the Macintosh operating systems. OSS
also provides synchronized audio capabilities
required for desktop video and animation playback.
