I Hear U 0.5.6

I Hear U is a Voice over IP (VoIP) application for Linux and it creates an audio stream between two computers in the easiest way and with the minimal traffic on the network.
I Hear U major features:
- Peer-to-Peer: the communication takes place between two computers without need of other servers and protocols in the middle.
- UDP/TCP support: IHU supports both UDP and TCP, with the possibility to choose UDP, for fast and easy connections, or TCP, if its the only solution when your computer is behind firewall or NAT.
- Good audio performance: IHU was born to give the best audio performance, low latency above all. For this purpose IHU is compatible with ALSA, now the default Linux sound architecture, but also with JACK, a low latency sound server. For the audio compression, IHU uses Speex, a codec optimized for speech (and completely free and open source).
- Crypted stream: you have also the possibility to crypt the stream using a fast hybrid cryptographic system (RSA + Blowfish)
- Command-line support: the GUI is not strictly necessary, you can run also a textual IHU from command-line (for example if you need to run the program on remote computers).
- Free and Open Source: IHU is totally free and distributed under the terms of GNU General Public License
The possibilities of use of IHU are infinite, for example you can use it like a phone to talk with your friends all around the world, or at home/work, to talk between computers in the LAN, etc., use it just as your phantasy suggests.
