DigitalMedia Presentation System with Acoustic Echo Cancellation
KEY SPECS: The audio processors help enable features such as acoustic echo cancellation
, noise suppression and beam forming in cell phones.
As part of its HD video conferencing cloud, the enhanced VoIP engine enables multiple participants to speak at the same time, and offers improved acoustic echo cancellation
support for laptops and better noise cancellation for superior audio performance during online video meetings.
Other features include data compression, echo cancellation
, noise reduction, conference calling for up to six people, call transfer, call recording, do not disturb, and a push-to-talk intercom.
* Acoustic echo cancellation
enabling full duplex calls.
Diva Server telephony adapters provide a full set of voice processing functions, including tone detection and generation, voice activity detection and echo cancellation
. Automatic gain control (AGC) is provided to automatically adjust the signal level of calls within a conference or for recording at normal levels.
The phone features advanced audio processing, full-duplex performance, distributed echo cancellation
and noise cancellation.--ClearOne Communications
Integrating unprecedented digital signal processor (DSP) power and network processing resources, Entropia III supports more than 1,000 VoIP channels on a single chip while concurrently supplying carrier-class echo cancellation
and a comprehensive set of telephony features.
According to Fastcomm, the FDX can provide greater throughput than symmetrical v.32 modems and it is less vulnerable to line noise since data can travel at 9600 bps in one direction and 1200 bps in the other without using echo cancellation
Yamaha's adaptive echo cancellation
and other unique high-quality sound processing technologies developed over the years also help facilitate a stress-free conversation.
The excellent noise suppression and echo cancellation
is based on advanced voice modelling techniques, allowing unwanted signals to be removed selectively.
