If you want to record from microphones and a Skype call for a podcast, you can download Soundflower to record computer audio and create an aggregate device with it and the audio interface responsible for your microphone(s). So what can you do with your aggregate device? If you have multiple audio outputs, you can use multiple sets of speakers to either pump audio into a different room or create a surround-sound setup. Once you’ve made your selections, you’re done! In the panel on the right side-side, choose any input and output devices you want to be able to access through this aggregate device.Double click on the name “Aggregate Device” to rename it (if you want to).
