Attached to this document is an electronic copy of the floating-point C code for the Immersive Voice and Audio Services (IVAS) Codec. This C code is the unique alternative reference specification besides the fixed-point C code for the IVAS Codec (3GPP TS 26.251) for a standard compliant implementation of the IVAS Codec (3GPP TS 26.253), Rendering (3GPP TS 26.254), Error Concealment of Lost Packets (3GPP TS 26.255) and Jitter Buffer Management (JBM) (3GPP TS 26.256).
The bit-exact fixed-point C code in 3GPP TS 26.251 is the preferred implementation for all applications, but the floating-point codec may be used instead of the fixed-point codec when the implementation platform is better suited for a floating-point implementation.
Requirements for any implementation of the IVAS codec to be standard compliant are specified in 3GPP TS 26.252 (Test sequences).
