Here is how I accomplish this using pulseaudio. If you go into OBS settings and set "Monitoring Device" in the advanced section of audio settings, it causes an audio delay. Leave OBS on the default monitor, it seems to detect the virtual speaker automatically and switch itself to it. Select "Remapped Monitor of Virtual Speaker" as your microphone in teams/zoom/etc

Turn monitoring on for one of your devices (it should play through your speakers/headphones to begin with)Ĥ. However, this causes audio lag so the audio is about 0.3 seconds behind the video. Pactl load-module module-remap-source source_name=Remap-Source master=Virtual-Speaker.monitorĬhristopher recommended going into OBS settings, and setting the monitor to the new device. # Now I need to take the monitor stream from the Virtual-Speaker and turn it into a source that Zoom can use Pactl load-module module-null-sink sink_name=Virtual-Speaker sink_properties=scription=Virtual-Speaker # turn on monitoring for the microphone and the video. Set it as the monitor device in Settings->Audio. The software runs on macOS 10.10 through 10.15 in 64 bit.# This created something I could see in OBS. If you’d like to upgrade to more channels, make one or two donations between 5 and 25 Euros, and you’ll receive personal download links for VB-Cable A+B and / or C+D. You can download the simple VB-Cable with one stereo channel for free, although the developer would certainly appreciate a donation. The developer says that the app works right out of the box, without the need for any additional configuration. It can handle sample rates from 44.1 to 192 kHz. Like the PC version, VB-Cable for Mac supports up to four stereo channels, labeled VB-Cable A+B and C+D. This functions like a virtual cable that lets you send audio from one app to another. Whatever you send into the input, comes out of the output at the other end. On Windows, VB-Cable became a popular solution, which has now been ported to the Mac.Įach VB-Cable is a virtual audio device with one stereo input and output. Newer alternatives are Blackhole by Existential Audio and Rogue Amoeba’s Loopback, for example.


Soundflower, which was initially developed by Cycling ’74, was the de-facto standard for this sort of thing on the Mac for a long time, but fell into disrepair. VB-Cable certainly isn’t the first application to let you do this. Or recording audio from your DAW or another source in a screen video. Recording audio from your browser or a VOIP app in your DAW, for example.

There are many cases in which you’d need to connect the audio output of one application to the input of another.
