Apps to mix sound files in real time, using two soundcards?

Can someone recommend some applications for linux to mix audio files (mp3, ogg) between two soundcards?
in realtime... you know, like DJs do, etc...

TIA, and sorry for the bad english

Re: Apps to mix sound files in real time, using two soundcards?

if you do not have two soundcards you have to use both channels of your only card splited...
so, you will have two different mono outputs...
with two soundcards you have full stereo, four channels
(and, maybe, more hardware power?, =slowliness... no idea...)

well, that is the idea...
(I do not know if it is well explained, technically)

Do you know something for one sound card Paul?

I think if you use more than one card at a time you're going to run into latency issues, since there is no guarantee that the output from two or more cards will be synchronized. If you really need more than two channels out, a better solution is to purchase a professional card with as many outputs as you need. Also, I don't think Jack (the standard for audio work in Linux) supports the use of more than one card at a time.

I can't think of a reason you would need more than two channels (one left, one right) unless you're trying to DJ in surround sound. Don't DJs using traditional gear just run a pair of turntables through a crossfader?

I haven't used the program, but Mixxx looks like the best Linux software for DJing. You might take a look at it first.

Thanks Paul... a few minutes ago I remember why to use two soundcards... with one you output music for people, with the other one you listen music, to select the next tracks.... if you have just 1, you need to make it mono...

I have instaled mixxx, thanks, lets see what happen

I understand. I completely forgot about monitoring. Still, one card with extra channels is probably better than two cards.
