Description:

IHU is a Voice over IP (VoIP) application for Linux, that creates an audio stream between two computers easily and with the minimal traffic on the network.

The main features are:

* Peer-to-Peer: the communication takes place directly between the computers (UDP and TCP both supported), without need of session protocols (such as SIP or H323) or other servers in the middle.

* 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 Encrypt/Decrypt the stream using a fast hybrid cryptographic system (RSA + Blowfish)

* Command-line support: the Qt 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 endless, 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 (talkback), etc.

 Win binary?

Hi! This sounds like a damn nice app! Can it be compiled on windows platform? If it can, can someone do that and put the link to the binary? Thanks!

I want to give it to my friend who uses Windows, to try it out...

Hi, unfortunately IHU binaries are available only for Linux at the moment. But it's possible to try IHU on Windows using the free VMWare Player. You can find the link to the HOWTO with the instrucions here:

http://ihu.sourceforge.net/news.html

HELP WANTED! If somebody would like to port IHU on Windows, any help is absolutely welcome! Please contact me.

I'm sorry, If I understand correctly, IHU is based on qt4, right? If it's true, than one should be able to compile it on win, am I right?

Yes, QT are available on Windows. But IHU uses also the ALSA library, which doesn't exist on Windows (afaik). So you should adapt the audio code that use ALSA to use the audio driver of Windows. I'm not a Windows developer so I can't tell further more, but It shouldn't be a big deal anyway.

Out of curiosity (and somewhat related), what are your thoughts about the SDL library? It’s a bit more portable than plain old ALSA, and I’d guess and since it’s used for games and other stuff, it should be quite low latency.

I personally never had much luck with getting Speex to sound good — on the other hand I messed around with GSM 6.10 once and it seemed really decent. The library is also free for any use as long as the copyright and disclaimer notice is retained intact. (http://kbs.cs.tu-berlin.de/~jutta/toast.html)

I didn't know SDL, it could be a good idea. I'll have a look, thanks for the suggestion.
Concerning the codec, I know that speex is not the best for sound quality but I'd prefer to continue to use Speex because it's totally open and free, and it's growing.

Yeah, I realised almost immediately that I was a bit ambiguous, sorry about that.

My comment about Speex was just a personal programming experience — I hadn’t yet had the opportunity to try your software so I can’t write any feedback on its sound quality.

GSM 6.10 was just a suggestion as a possible alternative, in case you’d like to add support for other codecs, as it too is free (as said, the only thing required seems to be attribution, other than that, you do what you want with it — which is even more liberal than GPL).

 Some suggestions

 
 by dunkelstern on: Nov 20 2007
 
Score 50%

Add dcop support and some kind of event handling or at least knotify integration and it will be perfect... No, just let me add one thing... Zeroconf integration would be great too, so you could fill the dropdown box with possible participants automatically.

Are there any plans to add webcam video? If you would plan that I would be the happiest person ever :)

I don't know how complicated it would be to port this to windows but it's worth a look. This could get an alternative to skype if done right (of course that would be a longer journey then :) )

I'll look into the code and check what has to be done to get it to compile on windows, I'll contact you if I know more ;)


KDE... because of the technology.

Thank you for your suggestions. I found interesting DCOP and Zeroconf integration.
Instead I think that I won't add webcam support for the moment, maybe in the future.

Please contact me if you're interested in the port to Windows!

Why dcop? The future is dbus as even kde4 will use it and not dcop anymore.

Nice would be to use phonon. AFAIK phonon will work on windows too

Yeah i heard there's a windows effort to port KDE libraries etc to windows.

We want to avoid KDE3 dependencies like DCOP thanks. Eventually KDE3 won't be supported anymore.

 Ports, Stereo, Keys, UTF-8

Yours Programm is very good. I like it. It is now in Gentoo Overlays VoIP.

Could You implement higher Ports, such as 65000, please?

And perhaps a Choise, for Mono or Stereo Speex Codecs.

http://www.speex.org/comparison/

A better Security, I am paranoic, Choise for a Random Keys with constant
Lenghts (bits) greater as 448, 4096 the Best.

Capabillity to write the Names in the full UTF-8 Letter, such as
čćžšđ, чћжшђ don't work
öä$ü works

Thanks smartnow

Development seems to have stopped :(
Hopefully someone can take over this fantastic app?!

Anyway there are not much apps in the "telephony" group, most of them not actuall and even twinkle is not based on Qt4 yet,... It's annoying!!!

How do you like Plasma 5?
 The best KDE Desktop ever.
 Definitely a nice improvement.
 Not decided yet. Haven't tried it yet.
 I do not like some of the changes.
 KDE is taking the wrong way.
 I am still sticking with KDE 3.5.
 I have no opinion, but wanted to vote anyway.
