BigSpeed Voice Chat SDK

Virtual private voice chat components

This program is a set of two POSSUINDO controls (Client and Server) that

lets you collection up a private voice chat 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 secret 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 particular server build a single private community.

Fine grained entry control is realized by a group of user-oriented permissions.

They grant entry control privileges to system resources and services in a flexible and safe manner.

The voice stream is highly compressed to deliver the best feasible sound more than a limited-bandwidth connection.

In addition, the typical bitrate is reduced thanks to the quiet compression. In the encoder, a voice activity detector with an adjustable induce level is used to distinguish between regions with normal speech activity and those with silence or background noise.

Significant replicate suppression is achieved using a robust double talk detector.

Capability to mute recording and mute playback is implemented.

The incoming and amazing audio data are obtainable in raw PCM file format for visualization in the software.

Two special events notify about signal overloading (possible distorsions) and transmission delays (network congestions).

Two different kind of text info can be exchanged between peers: alert and chat communications.

File transfer capability will be implemented for direct file exchange between peers.

This program uses a stylish event-driven paradigm with regard to easy integration into Windows applications. A special attention is paid to offer responsive user interface while avoiding multithreading problems.

Test applications are included in Visual Basic 2005 and Delphi 7.
