This TR presents the outcome of the Feasibility Study Phase of wideband Adaptive Multi-rate codec. Clauses 4 to 6 provide an overview and background for introducing AMR wideband. Clause 7 provides a review of relevant standardization activities. Feasibility aspects such as codec performance, speech coding bit-rates, implementation complexity and transmission delay are discussed in clauses 8 and 9. Clause 10 outlines the target timeplan for AMR-WB codec development, testing, selection and standardization. Clauses 11, 12 and 13 conclude with a summary of the risks and recommendations.
