I've been using my Mac, running Audio Hijack Pro, as a mixer of sorts. I primarily use it to increase the output volume since I like to compose with the volume cranked. I can also record, equalize, add effects, and whatever else. I'll probably just be using the software primarily for it's effects since I just purchased a nice mixing board.

Audio Hijack is $32, but you can get a decent mixing board under $100.

Agreeing with the above, the very basic answer to your question is "yes," but is it necessarily the best tool for the job? I don't think so but I'm not the one to answer that. (Coming from a person who recently decided that guitar-modelling amp-DAW is a better result than guitar-DAW-amp sim VSTs. YMMV)

Lol, low latency with Ardour.

But seriously, if you want realtime effects and EQing with low latency, you want JACK under Linux.
There are several applications for effects, etc, but here is a nice list:
- JACK Audio Connection Kit
- Patchage
- Rakarrack
- JACK Mixer
- JACK EQ
- JOST Ladspa/DSSI/Linux VSTi
- SooperLooper

You don't need all of these, and it isn't an extensive list, but it's a start.
If you choose to use JOST, I would run a search for LADSPA plugins, as well.

There are also Linux distributions with these (or similar) applications ready-to-go, such as Dreamstudio, Dynebolic, Ubuntu Studio, or Puredyne.

Or, you could buy a mixer.

EDIT: If you need to use multiple inputs/outputs, open a terminal and read up on alsa_in & alsa_out.

I agree with this sentiment, using just the computer might be a good temporary solution to eq'ing your tracks but if you want to play live that means you have to bring your computer, or if you want to use something other then one gameboy your stuck switching your only input around.  Personally i run all sorts of nonsense into my mixer, without at least 5 inputs id be a saaaaaad panda.

I'd think that EQing would have imperceptible latency on any well-configured audio computer. Under 10ms should be achievable. You could install a real time kernel, but I think the perceivable result would be the same for quite a lot of effort. Good idea though!

Better still would be to use a soundcard with a built in hardware EQ. This would have zero latency. A soundblaster or audigy (maybe with kX drivers) should be able to do it, I suspect there are plenty more. See: http://www.hometheatershack.com/forums/ … y-2-a.html

Any decent DAW software will do that, not just FL.

You can use fl-studio to do that, send the live input through one of the fx channels and add any plugins you like.  You will need a decent low latency sound card though.

don't use a mic in, they're almost always mono and are looking for a mic level signal, not a line level one, so they tend to add a little distortion to your signal. if you don't have a line-in jack, best bet is to buy a cheap usb soundcard at least, which tend to run $30+.. cheapest mixers with 3 band EQ are only about $10 more, so if the main purpose is for live EQ, mixer is probably a better deal (though youd still want the usb soundcard for recording, id think)

ah I always wanted to try ardour! how is it for recording live audio and applying effects live?

GB1 and GB2 goin' through a Toneport UX2, that goes to my macbook, then the stereo outputs from the Toneport go to the mixer.
At least that's how I do it.

Yes, that's why I said Windows Vista and Windows 7. Windows XP only has a mixer (though I've seen some drivers with simple treble/bass control), while Windows Vista and Windows 7 have what you are looking for - an equalizer.

It might be better to use an operating system with a real time kernel. Perhaps using Ubuntu & Ardour would be a good solution for keeping latency very low.

Mixers are cheap though, and you'd probably want one if ever playing live?

You're trying to use your computer as an EQ, not as a mixer
just a friendly correction

You really just want to get a D/A converter (audio interface) of some kind, game boy in, EQ VST like the one ant1 mentioned running, EQ'd gameboy out.

Personally, I would consider that two unnecessary D/A conversions and I would find a cheap EQ somewhere. The only real benefit of using the computer (assuming you use free software and already have an interface) is that it's free.

Hmm...I looked into this, and though I have XP I found a mixer for my soundcard. It doesn't seem to affect mic input though...
