JVOIPLIB 1.4.1

An object-oriented Voice over IP (VoIP) library written in C++ JVOIPLIB (Joris Voice over IP library) is based upon work done for a thesis at the School for Knowledge Technology (or School voor Kennistechnologie in Dutch), a cooperation between the Hasselt University and the Maastricht University.
A part of this library was developed at the Expertise Centre for Digital Media (EDM) in Diepenbeek, Belgium. The EDM is a research institute of the Hasselt University.
Main features:
- Easy VoIP session creation and destruction.
- Highly configurable sessions: sampling rate, sample interval, compression type, ... can all be selected by the user. These features can also be changed during a session.
- Openness and extensibility: the object-oriented nature of the library makes it very easy to add features; new components can easily be tested by registering them as User Defined modules.
- Support for 3D effects: for my thesis I also did some research and development about VoIP in networked virtual environments, which included adding 3D effects to sound. For this reason, Ive added this feature to the library.
- Currently, several components have one or more implementations. In this release, these modules are included:
- Soundcard input and output, file input and output (using libsndfile)
- DPCM compression, Mu-law encoding, GSM 13kbps compression (based on the GSM codec of Jutta Degener and Carsten Bormann), LPC 5.4kbps compression (based on the LPC codec of Ron Frederick), Speex compression
- RTP (Real-time Transport Protocol) transmission of data
- An elementary voice mixer
- A simple localisation scheme, a HRTF based localisation scheme
