Channel status and user data can be assembled in block sized buffers, making read/modi- fy/write cycles easy. Digital audio inputs and outputs may be 24, 20 or 16 bits. The input data can be completely asynchronous to the output data, with the output data being synchronous to an external system clock. Target applications include CD-R, DAT, MD, DVD and VTR equipment, mixing consoles, digital audio transmis- sion equipment, high quality D/A and A/D converters, effects processors and computer audio systems.
