- I.4 ZyXEL's CELP compression mode for voice
- --------------------------------------------------------------------------------
-
- CELP compression is currently available only on plus model modems. The
- implementation of CELP in the ZyXEL plus model modems is proprietary. As such,
- ZyXEL has not published any information regarding the manual decoding/encoding
- using this method. ZyXEL also will not confirm nor deny that the sources
- listed below will further elucidate the CELP decoding/encoding algorithms.
-
- Listing all the US Federal Standard 1016 sources is probably not too useful.
- The numerous pages of USFS descriptions do not help in decoding ZyXEL's CELP.
- They may help to understand what ZyXEL's CELP C code basically does. The
- USFS 1016 descriptions are nice to learn about what CELP *could* do ;-)
-
- For further understanding of CELP, it needs a real mathematician and deeper
- knowledge of voice processing theories.)

-
- The U.S. DoD's Federal-Standard-1016 based 4800 bps code excited linear
- prediction voice coder version 3.2 (CELP 3.2) Fortran and C simulation
- source codes are available for worldwide distribution (on DOS
- diskettes, but configured to compile on Sun SPARC stations) from NTIS
- and DTIC. Example input and processed speech files are included. A
- Technical Information Bulletin (TIB), "Details to Assist in
- Implementation of Federal Standard 1016 CELP," and the official
- standard, "Federal Standard 1016, Telecommunications: Analog to
- Digital Conversion of Radio Voice by 4,800 bit/second Code Excited
- Linear Prediction (CELP)," are also available.
-
- This is available through the National Technical Information Service:
-
- NTIS
- U.S. Department of Commerce
- 5285 Port Royal Road
- Springfield, VA 22161
- USA
- (703) 487-4650
-
- The "AD" ordering number for the CELP software is AD M000 118
- (US$ 90.00) and for the TIB it's AD A256 629 (US$ 17.50). The LPC-10
- standard, described below, is FIPS Pub 137 (US$ 12.50). There is a
- $3.00 shipping charge on all U.S. orders. The telephone number for
- their automated system is 703-487-4650, or 703-487-4600 if you'd prefer
- to talk with a real person.
-
- (U.S. DoD personnel and contractors can receive the package from the
- Defense Technical Information Center: DTIC, Building 5, Cameron
- Station, Alexandria, VA 22304-6145. Their telephone number is
- 703-274-7633.)
