 GHI Voice Codec Suite |
|
Features:
- Innovative codec architecture with proprietary patented technologies.
- A full set of codecs, ranging from narrowband codecs to wideband codecs, standard codecs to proprietary codecs at different rates, tailored for different application.
- Automatically select tradeoff between bit-rate and voice quality to deliver decent quality for both low bit-rate and high bit-rate connection.
- Bit-rate and codec structure adaptive to network conditions.
- High voice quality even under 30% packet loss environments.
|
WBVR |
Wideband proprietary codec, variable bit rate (0 to 34kbps), optimized for traffic and channel usage, robust in adverse network condition, adaptive to network conditions. |
|
AMR |
Improved standard codec AMR targeting for wireless application.
Discontinuous Transmission (DTX) supported |
|
G.711 |
Enhanced standard codec G.711 targeting for PSTN call with superior packet loss robustness. |
|
G.729 |
Narrowband. Fixed rate 8kbps. Compatible with ITU standard but with complexity reduced significantly. Specially useful for embedded application. |
|
G.723 |
Narrowband. Fixed rate 5.3kbps, 6.3kbps. Compatible with ITU standard but with half of its complexity. Specially designed for embedded application. |
|
NBVR |
Narrowband codec, variable bit rate (0 to 24kbps), optimized for traffic and channel usage, robust in adverse network condition, adaptive to network conditions. |
|
NB13 |
Narrowband codec, fixed rate 13kbps, low complexity with clearly better quality than G.729, for application with limited channel resource but need high packet loss robustness. |
