I know Rogue Amoeba is in the news the past two weeks for other things but I thought this was cool. If you already own a Rogue Amoeba app you can get SoundSource for free.
SoundSource is a handy little menu app1 that provides more detailed controls over input and output.
Of course, if you don’t already own any Rogue Amoeba apps then you can still buy it for $10.
Technically it can also be a dock app too, but only depraved monsters use it that way. ↩︎
