I use Soundsource for specifying which audio interface an app should use to play its audio output. But it only works for output, not input. Is this a system limitation, or is anyone aware of an app that lets you do the same for audio input?
(My use case is that I want to use my Studio Display microphone for most things, but use my headset for phone calls with my VOIP app)
SoundSource lets me set audio Input… what am I missing?
Alternatively you can use the “Audio MIDI Setup” app which comes free with your Mac; it lets you create an “Aggregate device” which includes both inputs and outputs (or multiple selections of each simultaneously).
I’d like to set the input automatically per-app, like you see down at the bottom of your screenshot for output. The part under “Applications” in the screenshot is only for directing output, not for selecting which input (i.e., which microphone) to use in each app. So I can’t set a different input for Zoom, for a VOIP app, etc. They all have to use the same microphone unless I manually switch it.
Thank you. Maybe I’m not understanding this thoroughly, but wouldn’t this run into the same issue of Soundsource only pointing to one input at a time? In other words, even if create multiple Aggregate Devices, I can only point to one of them at a time? Or are you saying that by combining an input and output into one aggregate device, I can point to it as an output and it will use the paired input I set up as an aggregate device, and I can ignore Soundsource’s input setting?
Totally going off the top of my head here, but I think most (all?) apps that take audio input should have a setting to say which? I know MS Teams and Skype do, for instance.
Even if some don’t, if you want ‘most things’ to use the SD microphone, then set that as your system input, and set your VOIP app to use the headset. Certainly with the two I mentioned that setting will stick if the headset is plugged in when the app starts (in the case of Teams).
