About Adaptive Multi Rate - WideBand +
AMR-WB+ is an audio codec that extends a speech coding standard AMR-WB (Adaptive Multi Rate - WideBand). AMRWB+ adds support for stereo signals and higher sampling rates. Another main improvement is the use of transform coding additionally to ACELP. This greatly improves the generic audio coding. Automatic switching between transform coding and ACELP provides both good speech and audio quality with moderate bitrates.
AMRWB+ supports various internal sampling frequencies ranges from 12.8 kHz to 38.4 kHz. |
