Capture sound card audio?

Is there a way to capture audio directly from the outputs of my sound card with MaxMSP?

No, unfortunately adoutput only captures signal coming from MaxMSP. What I want to be able to do is capture any and all audio being sent to any and all output channels on my soundcard.

Yes, its called "cable" and is not software, best used in combination
with a tool called mixer (also not software… ;-)

If you want to capture only what MSP is putting out, you can use adoutput~.

Elsewise try Jack, which can route and mix any soundsources together and
feed it into Max. It works well on OS X, and I know there is a Windows
version in developement at least in beta state…

Yeah, but Patching my outputs to an input is too messy, plus it adds unnecessary noise and ADC/DAC converions, and I do know what a mixer is. I’m trying to poll my overall output amps.

I’ve been using JackOSX, but it’s not great about finding certain apps that may start and close while Jack’s started (Audacity,Firefox,etc). Any news on when a better port of the linux qjackctl is going to be out? now that’s a tool I could use… and then you’re not really polling the output to your soundcard device, so determining the overall amps going out just exponentially more messy.

soundflower from C74?

http://www.cycling74.com/downloads/soundflower

i’ve managed to get itunes to play through soundflower driver (set via system prefs/sound) and back into msp (set DSP status / input to receive from soundflower).

but its only for macosx…

There are only two ways to get this, one is Apple is providing a
seperate driver which grabs the audio form the sound card, which is
hardware dependent and too messy to be something to hope for (there is
no practical use for the average user for this feature)
The second is to script/program Jack or Soundflower in a way, that it
provides the output automatically on a seperate bus. That’s much more
likely to be possible. Jack as well as Soundflower are open source,
maybe somebody who needs it desperately will dive into the code…
(its not me… ;-)
