The Bit Stream Detector (for S/PDIF) library is used to differentiate among S/PDIF structured audio bit streams. S/PDIF is a Digital Audio Interface that can encapsulate a combination of encoded or uncompressed audio bit streams in a standardized block format. Each S/PDIF structured block contains unique stream type information which can be detected and used to invoke the relevant decoder such as Dolby® Digital (AC-3), DTS, MPEG Audio and WMA Pro.

- This table highlights expected MIPS performance. MIPS figures can be affected by changes in code and data placement in memory.
- MIPS were measured using the following configuration:
- Processor: ADSP-BF533, ADSP-BF548, ADSP-BF527
- Input buffer size of 8192 bytes
- All code and data were placed in L1 memory
- Worst-case input test vector, recorded from a range of DVD players that support DTS, AC3, PCM S/PDIF output.
- Instruction and Bank A data caches enabled and configured in write-through mode.
- In the table above all figures refer to one instance of BSDET. "Data RAM" includes stack, instance state and input buffer.
- Heap (or "malloc()") is not used.
- 1 KiB = 1024 Bytes.
