  1. Go to your System Preferences / Sound and select the Multi-Output Device as your main Audio Output. Now you can play sounds from any of your Mac applications, send them to OBS via BlackHole and monitor those sounds through the Master Device you added to your Multi-Output Device (in this case the MacBook Pro Speakers).

    3. Adjust the levels between Mic/Aux (your voice) and the Audio Output Capture (your DAW and all other audio sources) **in the Audio Mixer window. Note that you won't hear your mic, the easiest way to check levels in that setup is to record the OBS output and listen back to the file. You can also check sound levels before going live in Test My Stream page or your session cockpit but there will be latency (read the section is FAQ about adjusting sound level for details).

      <aside> 👉🏼 Don’t be afraid to go in the yellow and even red on the OBS meters otherwise your sound may be quite low for viewers.

For better control over your microphone sound

This requires a computer and soundcard powerful enough to have low latency in your DAW.

  1. Route all your tracks in your DAW session to a new Audio Track (in Ableton Live) or Bus (in Logic Pro). Let’s name this Bus Track the “Mix Bus” (and activate “Monitor In” if in Ableton).
  2. Create another track and name it the “Mic Track” :
    1. Select your USB or built-in mic as the audio input.
    2. Activate monitoring for this Mic Track to be able to hear it (with headphones on to prevent feedback loops).
    3. You may add compression, noise gate or any plug in you’d like to make your Mic sound great.
    4. Route the Mic Track to the master.
  3. Find a balance between the Mix Bus and the Mic Track without overdriving your DAW master so we can hear you and the music clearly on the live stream.
