SoundSource 4 supports macOS Dark Mode and includes an option to display the output volume indicator on the menu bar just like the current Sound preference setting. The software makes it easy to switch between input or output sample rates-that is, unless you have dedicated video hardware which locks the output sample rate at 48Hz. These advanced options are tucked away out of sight, accessible by clicking the right-facing arrows next to each device or application.

That’s right-if you already have AU plug-ins installed on your system, they’ll now work directly in SoundSource 4 straight away, while the equalizer includes over 20 presets with the ability to create and save your own. Per-application audio controls allow SoundSource 4 owners to route sound from different software to as many devices as you have.Įven more cool, each output comes equipped with a 10-band Lagutin equalizer, balance slider, and the ability to apply Audio Unit effects. This amazingly powerful addition comes configured with a selection of sound-producing apps when you install SoundSource, but others can easily be added, with drag-and-drop support for arranging icons in any order you like. This allows users to raise, lower, or mute the output of individual apps, enable Magic Boost only for specific software, or redirect apps to a different output altogether. If that’s all SoundSource did, it would still be worth the money, but version 4.0 kicks things up a notch with per-application audio controls.

Aside from choosing a different system sound effect, you’ll never have to open Sound Preferences again, but the settings gear includes convenient shortcuts to those options as well as Audio MIDI Setup, should you need it. By default, SoundSource tethers to the menu bar, but clicking the pin icon in the upper left corner conveniently detaches the window so it floats over whatever else you’re doing.
