The VoLTE supports HD voice over AMR-WB
networks and requires sophisticated testing for both voice and data quality.
HD Voice is enabled by wideband codecs, with AMR-WB
designed specifically for VoLTE, and mobile voice networks.
Mobile carriers are starting to roll out the AMR-WB codec in their networks, bringing excellent audio quality to their customers.
AMR-WB is the only wide-band codec standardized for both wireless and wire-line applications and hence is the natural choice for delivery of HD-voice calls over the converged fixed-mobile network.
We value TranSwitch as an important collaborator in the promotion of our AMR-WB Technology to our mutual customers", said Richard Romagnino of VoiceAge.
Moreover, also helps in giving backings of several range of industry standard codecs like AMR, AMR-WB
, EVRC and more.
Audio For Newsgathering: Working representatives from this elite, unique and occasionally dangerous branch of the audio world are encountering a constantly expanding universe of options for gathering and broadcasting news: From EV-DO to BGAN, AMR-WB
to HE-AAC, CF to SDHC, this session will move beyond the acronyms to investigate current and emerging options for audio field recording and "backhaul.
Ericsson, which jointly holds the patent for Adaptive Multi-Rate Wideband (AMR-WB
) technology on which HD voice is based has been offering HD voice for several years, but it has only been in the past 24-36 months that many networks and terminals have adopted AMR-WB
Voice codecs include AMR-NB (narrowband), AMR-WB
All the above software modules run on the ZSP400 processor and corresponding reference silicon (including VSI403LP, VSI403US, VSI407LP, VSI407US) and include advanced voice technology, such as AMR-WB
