if you have the hardware, and easy way to do this on the software side would be to have a separate machine, some cheap laptop would do the job, and some kind of mixer... you could route the track into the mixer from whereever, and a microphone, and pipe that into the machines sound card that is running BUTT... that would combine the sources and doesnt depend on JACK at all... you could do this with a CD or mp3 player too with a mixer going into one computer (if you prefer the one computer rig)... even in JACK, its going to be challenging if your using an onboard sound card... you might think about splitting the channels left and right and thinking about it more like a 2 track audio device... put the music on one input (mono) and the mic on the other, and mix those in something with JACK and output to whatever... now that i think about it, IDJC would be nice actually because it blends the music and a mic input.. why was that not working for you? the mic latency didnt match the track?... i have only noticed the mic input in IDJC and didnt really try using it..<br>

Yes, sorry, I didn't supply enough details. Basically its me
singing over a pre-recorded music track streaming into a shoutcast
server (which I already have running remotely). So basically I need
to mix a prerecorded stream with my voice and broadcast that to an
external shoutcast server.<div class="im"><br>

<div>i would say the best way to do this would be darkice from
JACK to an icecast server... i think the easiest way to do this
would be using the B.U.T.T. (broadcast using this tool)
client... IF you need to play the file, and have others <i>not</i>
on your local network sing over them, i would suggest looking at
netjack or jacktrip, (but those are difficult to get going) or
the simpler <a href="http://mumble.sourceforge.net/" target="_blank">http://mumble.sourceforge.net/</a>
... mumble is cross-platform too... <br>

Mumble is interesting and I can think of some creative uses for that
with SecondLife but thats overkill for what I need now. I'll have a
look at darkice and B.U.T.T. In the past I had issues trying to
figure out how to get the stream *into* BUTT but I'll have another
look.<br>

audio (into SecondLife for a open mic performance). I have
jack running<br>
(and pulseaudio running through it) and have used IDJC
successfully to<br>
stream. I really haven't been able to use that to sing live
because I<br>
get a small but very obvious delay in the vocals. I thought
there must<br>
be a way to do software mixing similar to what you'd do in
hardware:<br>
that is playing the karaoke track over headphones and adding
my voice<br>
mixed down to one stream, then thats fed to IDJC. If I have
to I can<br>
pre-record the tracks though I'd really prefer a live setup
if possible.<br>
<br>
Can anyone offer any suggestions or pointers to howto's to
set up a<br>
system for live performance like this?<br>
<br>
Thanks!<br>
