Abstract
An architecture allows two-channel sound effect hardware to output four-channel analog signal, comprising sound effect application program for processing multi-channel information of application software. An operation system kernel program is received the multi-channel information by a multi-channel sound effect interface. Means for transforming a four-channel signal to two-channel signal is coupled to the operation system kernel program to transform a four-channel information to a two-channel information. A two-channel sound effect hardware is coupled to the means for transforming a four-channel signal to two-channel signal. A converter is coupled to the two-channel sound effect hardware to transform the two-channel signal to a four-channel analog signal.
