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

Great gist.. are you able to adjust the speaker output volume when you have the output device set as 'Dual Output'? macOS doesn't let me adjust the volume - though it's left at the setting before you switch to the dual output mode, so not all bad

Thanks for the tutorial. 🎉

I can confirm that without headphones it works it also works with my headset that is not apple.
Making it work is a real pain. :(

meet.google.com (Google's "Hangouts" for business) has a recording feature built-in that accomplishes all of this now 🎉
That's what I've been using lately, since we use gmail (etc) at Heroku 🙂

I installed soundflower and configured everything according to instructions, but unfortunately quicktime will only record my mic.

Wow. I have Soundflower installed on my Mac but never got to try this. I have been looking for a way to record two-way audio like this to no avail. Thank you so much for such clear and detailed guide. I set it up and it worked! Didn't know Soundflower is such an amazing tool. I confirm this works on Mac OS Sierra 10.12.6. The voice chat app I used is LINE, and I used earphones for my voice input.

I wonder if a similar tool/solution exists for Windows.

Again, I am so thrilled to have found this solution. Thank you for sharing your guide!

Thank you!!! It works on my macbook pro with headphones.

I want to use microphone + system audio (playing audio file) into Google Hangout Microphone Input. I also want to record Google Hangouts audio output + system audio output (audio file) + microphone on QuickTime. I want to be able to hear the audio file and the Google Hangout output. How can I achieve this on a Mac using SoundFlower. Any suggestions?

Works with Skype on Mac (Mojave) as well (using "Default Device" for input and output) 👍
