Quicktime + Hangouts Recording

Scenario: You want to talk with someone over google hangouts (like for a user study), and you want to record BOTH:

the system output audio (from them)
the microphone audio (from you)

(screenshots below in a comment)
General Setup (do this once)

1 Install Soundflower

brew cask install soundflower
(if you don't have/use brew, then google soundflower and install it from their site~)
2 Make an aggregate device (for quicktime input)

This is for Quicktime to be able to record audio from both you and the other person.

open the OSX system app Audio Midi Setup
Create Aggregate Device
Include both inputs:

Built-in Microphone
Soundflower (2ch)


Name this one Dual Input for Quicktime (optional)

3 Make a multi-device output (for output)

This is so both you and quicktime (via the aggregate device^) can hear what's going on.

open the OSX system app Audio Midi Setup
Create Multi-Output Device
Include all both outputs:

Built-in Output
Soundflower (2ch)


Name this one Dual Output (optional)

Specific Setup (do this for each screen recording)

4 Choose system output


alt-click on the volume icon in the taskbar
choose your system

input = External Microphone (hangouts only needs one - quicktime will get both on its own)
Output = Dual Output (hangouts should output to both quicktime and your headphones)


5 Quicktime screen record


Open Quicktime Player

(you may need to close and re-open this after configuring inputs)


File -> New Screen Recording
In the dropdown next to the record button

Microphone = Dual Input for Quicktime
