Soundflower lets you loop the audio from your system output to your system input. Once it's installed, launch the controller app (actually called Soundflowerbed; note that, as of the time of this writing, the app is no longer distributed pre-built; you must download the Xcode project from the GitHub page above and build it yourself). You will get a flower icon in your menu bar; from it, select "Built-in Output" under the "Soundflower (2ch)" section (the "64ch" part doesn't matter). Then go to System Preferences>Sound, and under both the Input and Output tabs, choose "Soundflower (2ch)". This is the software equivalent of the audio cable loop method described below. | |||
Now, if you want to have passthrough audio, so that you can actually hear the game while playing and recording it, you need to go an extra mile. First, plug in some headphones. Then, open OS X's Audio MIDI Setup app (which can be reached by choosing Soundflowerbed's "Audio Setup…" menu item), click the "+" button at the lower-left, and create a new "Multi-Output Device", then check the "Use" box for both "Built-in Output" and "Soundflower (2ch)". Then, expand the Multi-Output Device item in the left-hand list of the window and select the Built-in Output sub-item. You'll want to turn the volume for channels 1 and 2 down to -33dB or lower in order not to blow your ears out (OS X doesn't automatically dampen the volume for headphones when they are part of a multi-output device). Note that once you are recording, you won't simply be able to adjust the headphones' volume from the speaker icon in your menu bar; it will be grayed out because OS X cannot set the volume for multiple devices at once. Finally, go back into System Preferences>Sound, under the Output tab, and choose "Multi-Output Device" instead of "Soundflower (2ch)". | Now, if you want to have passthrough audio, so that you can actually hear the game while playing and recording it, you need to go an extra mile.
