Bradon Technologies Ltd has designed and implemented a new concept in VoIP
(Voice-over-Internet-Protocol). This proprietary technology demonstrates
significant improvement in voice transmissions over unstable, high latency
networks such as the Internet. It provides real-time connection for any type
of voice conversations over the Internet including multi-user conference calls. Bradon’s technology
makes available voice synchronization with any other concurrent contents
(lips synchronization issue) along with excellent voice quality and extremely
low bandwidth. This all became available with a new approach of the voice
compression – BTAC. BTAC, the voice codec
BTAC - Bradon Technology Audio Codec is a frame independent codec. It means
that each frame is encoded and decoded independently of past frames.
Every packet that arrives can be perfectly reconstructed right away.
The codec utilizes full 4kHz frequency band range and delivers excellent
voice quality. It has 4 bit-rates 2.4/4.8/9.6/19.2 Kbps with a sampling
rate of 8kHz. BTAC perfectly works for voice-over-the-Internet
communications. BTAC has extremely low overhead. This is very significant
for channels with a limited connection capacity. Figure 1 shows the
bandwidth chart comparing BTAC with other audio codec.
The BTAC is at the heart of all of Bradon's online communications products.
This proprietary technology combined with SAVii™'s features and easy to
use software give Bradon a clear advantage over other online conferencing
tools.
