I forgot to tell you that you have to change the directories for PLIB
and OPENAL in the Makefile (line 26 and 27)...

Hi,
I am just amazed how nice bad sound can be if you try to use it in a
radio environment :-) Every VoIP'er thinks I am braindead because I try
to make VoIP streams sounding worse and not better...
Csaba ported the openal code to iaxclient2 and Tat enhanced the Makefile
so FGCOM builds on MacOSX. I added software DSP support (noise
generator, filters (high, band, low, ... - but the algorithms are not
highly optimized) and a simple squelch simulation (which has some small bugs).
Currently all parameters for sound de-optimization are hard coded.
All together it sounds really bad :-> . Try it, but don't blame on me if you
have trouble to get it working - it's a _pre_ release!
svn checkout svn://svn.dfn.de:/fgcom/branches/iaxc2-lofi fgcom-lofi
There is much to do and I hope there are some hackers around who likes
to take part in the next steps of development:
- fixing the squelch code. The noise gate is poorly implemented...
- installing an interface for the dsp functions in the library code.
This is really not difficult but takes some time to organize...
- enhancing the algorithms of the dsp stack (avoiding multiple loops for
a block of samples). The dsp stack should be flexible configurated from
the fgcom application/config file so that the sound can be flexible changed
to simulate different kinds of radios.
- due to more and more parameters: using of a configuration file
would be great - perhaps one in XML which uses code from FG to parse
the XML data?
- mixing background noise from the plane machines (perhaps pending on
the state/level of the machine) into the outgoing stream
And also on the queue:
- intercom (I have a very simple solution for that - but no time to
write code for)
- a better conference application based on distances of the objects and the
power of the radios
Anyone who likes to help :-) ?????
Have a nice weekend!
Regards, Holger
