I am wondering if there is a program that will allow me to record my mumble converstaions.... If not I wonder if this is a feature anyone has thought to add?

Look at the feature request tracker. It has been requested and we are thinking about adding recording capability. No promises though. It's not yet on our todo.

Know of any alternative programs to use along side with mumble?

same interest for me :)

I wish the developers will add this function when they can, and while waiting
that, any one know a software working with mumble to do that ?

I only know software which can record from the active recording source.
So you could no longer talk while recording.

I do wonder however, and would like such a program or anything, so I could
record output and still talk.
That'd also come in handy when making videos of games and such, as I always
have to adjust volume when switching from mic to out as in and it's never the
same nor optimal.

When I want to record a conversation on Mumble I just use Audacity on the
server with a client running. The mostly obvious settings would be to record
output audio in Audacity and mute input on Mumble. Also recording volume would
more than likely need to be adjusted considerably below the max. You could
also use a system separate from the server, but generally the closer it is to
the server the better to reduce potential connection issues affecting the
quality.

The advantage of Audacity over a built-in method is that it can record at the
best possible quality and export in just about any format you'd want. A built-
in recording feature would probably be limited to one format such as MP3 which
is more or less lossy or WAV which is uncompressed (can easily get very
large). Personally I would prefer FLAC which is lossless with good
compression, but it would probably confuse a lot of people and it might not
play in some common players.

The advantage of built-in is that it would be easy to do with limited
resources. It would of course work similar to recorders built into other voice
chat clients like TeamSpeak where it records both input and output, since both
are being passed through Mumble anyway. That means not only can it capture
both at once and compile it into a recording, but it only captures the output
that goes through Mumble, leaving out sounds from other programs.
Theoretically it might even be able to record every user on a different audio
channel, which would be a HUGE help to podcasters (example: edit out a cough
while someone else was talking).

So in summary, there are trade-offs between external vs. built-in recording,
but if we get built-in it's just an extra option and not a replacement. I like
options and I think built-in recording would help many people such as
podcasters, but personally I don't have much reason for it yet (I'm sure I'd
find one though, like restarting my podcast).

Just my 2 cents, but maybe it would be good to just request a plugin system on
the server side that could support a plugin for recording.
Heck, another plugin to connect to a SIP server so people could dial in and
use it for conferencing or to let their gamer buddies know they were running
late. Maybe a plugin that links to a ventrillo server or teamspeak server
bridging channels. ok, enough silly rambling.

@michaelminor: If you want to increase the chance that we will implement such
a thing anytime in the future you should feature request it. Otherwise we the
chance that we think of it when we decide on new stuff to do is relatively
low.

@dd0t: I would if i knew I would use them. I think they are interesting ideas
which is why I brought them up, but I will leave the feature requesting to
those who really might use them rather than might dabble with it down the
road, which is what I would do.

@michaelminor:
With Google Voice coming into the picture, a lot more people might be able to
use a SIP feature. There are also SIP access numbers that have been around
awhile. Implementing it properly would be a bit of a challenge I'm sure.

The Vent/TS bridging might be good or bad, showing people how capable Mumble
is but possibly also preventing people from moving to Mumble since the feature
is most specifically for those people who don't want to switch. Also such a
feature would need to be entirely independent of Vent/TS to avoid lawsuits or
any of that, just the ability to bridge audio between Mumble and another
application.

Try using gomeetnow webinar service. It records screen and voice using your computer's microphone. The resulting recording is stored as an executable file which contains both the recorded data and a built-in player.
