Fraunhofer IIS has announced that its Full-HD Voice codec, AAC-ELD, will be avilable to application developers and service providers wishing to create VoIP applications with high quality audio.
The codec has been supported natively on iOS
and Android for some time, but will now be
made available to the wider market.
VoIP applications typically
offer 3.4 kHz bandwidth, similar to legacy telephone systems,
whilst some more recent offerings have reached 7 kHz. This
is still far below the 20 kHz range of
human hearing.
The AAC-ELD codec now offers this full
20 kHz of bandwidth, meaning that voice, background noise
and music can all be treated equally in IP streamed audio settings.
