Audio routing

Garrett's icon

Hi

I'm trying to route audio from one application through max and then on to a third application which is recording that sound and visuals from the screen into a single video, so:

visuals       ->     recording application
                              ^
                              |
sound   --->   max   --->

Most things things I read about Soundflower discuss two applications, I'm getting feedback every way I try, is it possible to do this configuration or is there an alternative solution? I have a second computer would that or an extra soundcard solve this? Passing through analog and back isn't a problem but I'm just having trouble visualising this.

thanks in advance

I use JACK for my inter-application audio routing needs.

It's controllable with the JackOSX JackPilot GUI, or with command line tools you can invoke from within Max with the shell object (jk_lsp, jk_connect, jk_disconnect). I have all my JACK abstractions handle their own I/O in this way.

Hi

Thanks for this, took ages of fiddling to figure out how to route things correctly but it seems the first app in the chain (sending audio) is a problem as its sending can only be sent through the system and that gives feedback. Still trying, perhaps some combination of Jack and Soundflower will work.

Hi,

EasyMac, could you be more specific about how you use shell objects to have jackOSX abstractions? could you give an example? got lost there.... :-(

Hi miguelvb, I don't know if this is exactly what you are asking, but this post could be of some interest:
