^{Buffer Chains}

A sound does not necessarily go through only a single secondary sound buffer. It is possible for buffers in an audiopath to send data to other secondary buffers. The advantage in doing so is that sounds from multiple buffers can be directed to a shared buffer where common 3-D parameters or special effects can be applied. Shared buffers can also be more efficient.

Buffer chains are set up automatically when an audiopath is created from an audiopath configuration embedded in a DirectMusic Producer file. For more information, see Using Audiopaths.

Buffer chains cannot be created by using the DirectSound API.
