Summary

Annex C to Recommendation ITU-T G.722.2 specifies the bit-exact ANSI C-code implementation of the AMR-WB algorithm specified in Recommendation ITU-T G.722.2, its Annexes A and B, and its Appendix I (non-normative).

This annex includes an electronic attachment containing the C-code of the G.722.2 AMR-WB speech transcoder. The C-code has been updated to harmonize with the AMR-WB coder in 3GPP specification TS 26.173 V14.0.0 (2017-04).

Corrigendum 1 details a number of minor corrections to the capitalizations of certain file and table names in the description in Table C.5 used in the C-code in Annex C of ITU-T G.722.2.  These changes harmonize Annex C with the AMR-WB codec specification, TS 26.173 version 14.1.0 (Rel‑14).

The changes are only relevant to the text of Annex C and not to the source ANSI-C code of its electronic attachment.
