Zoom does offer some visual enhancements such as blur effects and filters, but OBS offers much more flexibility. One of the most popular ways to use a virtual webcam output from OBS is with software such as Zoom. Use cases for virtual audio and video connections vary widely. These virtual audio and video connections allow you to use OBS with any software that leverages a standard webcam and microphone input. OBS is also capable of using virtual audio cables to connect audio from OBS to other applications on the same computer. OBS is capable of outputting a virtual video camera which can be used with software like Zoom as the webcam input.

This is where virtual video and audio cables come into play with OBS. Many people who use video communications software, would like more control over their audio and video, but only have the ability to use a webcam and microphone as audiovisual inputs. Zoom used this mix as input.OBS has become a popular production solution for people who use video communications software such as Microsoft Teams and Zoom. The volume levels of the two microphones can be mixed in obs. You find it in 'Advanced Audio Properties' for the microphones.įinally, in the Zoom settings, select the BlackHole audio device as microphone. This will route the signal to the BlackHole device. In obs, for both microphones, you need to activate 'Audio Monitoring'. In the obs settings ( Cmd+,), under 'Audio', under 'Advanced', select the BlackHole audio device as 'Monitoring Device'. Then add the second microphone the same way in obs. In obs, in the 'sources' section, add the first microphone as 'Audio Input Capture'. Unfortunately, I didn't manage to get it working with Apple GarageBand, because this couldn't handle both microphones simultaneously. You can use Apple Logic Pro if you have it, or you can use obs (free). Install a mixer software that will be used to combine the microphone sources. Install the BlackHole virtual audio device brew install blackhole-2ch Install the homebrew package manager /bin/bash -c '$(curl -fsSL )' But as BlackHole has been mentioned in the comments, let's try this one:īlackHole is a modern MacOS virtual audio driver that allows applications to pass audio to other applications with zero additional latency. Originally, I was thinking of soundflower ( brew install soundflower) or vb-cable ( brew install vb-cable), maybe in addition to obs ( brew install obs) for mixing. Using a virtual audio device and a mixer software, one could mix the different microphones together into one channel of the virtual device and then select the virtual device as microphone in Zoom. Zoom might pick up only the first channel of the aggregate device rather than mixing all the channels together. The problem with aggregate devices in macOS is, I think, that the different input microphones will be assigned to different channels.
