Mixer
Architecture
The basic
element of the mixer architecture is an audio line. An audio line
consists of one or more channels of data originating from a single source or a
system resource. For example, a stereo audio line has two data channels, but it
is considered a single audio line because it originates from a single source.
The mixer
architecture provides routing services to manage audio lines on a computer. You
can use the routing services if you have adequate hardware devices and software
drivers installed. The mixer architecture allows several audio source lines to
map to a single destination audio line.
Each audio
line can have mixer controls associated with it. A mixer control can perform
any number of functions (such as control volume), depending on the
characteristics of the associated audio line.
