BigSpeed Voice Chat SDK is a arrange of two COM controls (Client and Server) that
lets you arrange up a private articulation confabulate network for safe messaging.
The transfered data are scrambled using on-the-fly 128-bit AES encryption. The security is provided in two different modes: symmetric encryption with shared enigma key and asymmetric encryption with 1024-bit public / private keys.
The server is responsible for keeping information on and authentication of online peers.
All peers connected to a special server flesh a single private community.
Fine grained access control is realized by a group of user-oriented permissions.
They grant access control privileges to organization resources and services in a elastic and safe manner.
The articulation pelt is highly compressed to return the outflank possible intelligent over a limited-bandwidth connexion.
In improver, the average bitrate is reduced thanks to the muteness compaction. In the encoder, a articulation activity detector with an adjustable trigger charge is used to discover between regions with normal speech activity and those with muteness or setting noise.
Significant echo suppression is achieved using a robust double talking detector.
Capability to muffle recording and muffle playback is implemented.
The incoming and outgoing audio data are available in crude PCM format for visualization in the application.
Two special events notify almost signal overloading (possible distorsions) and transmission delays (network congestions).
Two different openhearted of text information dismiss be exchanged between peers: alert and confabulate messages.
File transfer capability is implemented for engineer file commute between peers.
BigSpeed Voice Chat SDK utilizes an elegant event-driven paradigm for facile integration into Windows applications.A special attention is paid to ply responsive user interface while avoiding multithreading problems.
Sample applications are included in Visual Basic 2005 and Delphi 7.
