libraries are needed to perform the necessary voice handling tasks.
EditBy: Usually, when a VoIP application is being developed, several software libraries are needed to perform the necessary voice handling tasks. The purpose of this SDK is to provide integrated, one-stop solution for audio Capture/Playback, voice compression/decompression, and audio pre/post-processing. Thus, a Visial Basic or other COM-enabled language programmer can quickly develop a VoIP application by just adding the necessary data exchange/network code.
