DirectSound Buffers

DirectSound buffer objects control the delivery of waveform data from a source to a destination. The source might be a synthesizer, another buffer, a WAV file, or a resource. For most buffers, the destination is a mixing engine called the primary buffer. From the primary buffer, the data goes to the hardware that converts the samples to sound waves.
