# Open source
## gladstone
GladSToNe is an educational tool for learning about hi-performance audio handling for real-time transmissions. The goal of the project is to use the open source model to improve the psycho acoustics, noise shaping and speed of audio transmissions over IP. Contains a G729 codec plugin, **g729enc** for encoding and **g729dec** for decoding.
* [[Project page on Google Code|http://code.google.com/p/gladstone/]]
* [[Code repository on Gitorious|http://gitorious.org/gladstone]]
