Rogue Amoeba has undated SoundSource, a macOS tool that provides access to critical audio settings, to version 4.1. With the app, users can:

  • Control audio on a per-app level, adjusting the volume of any app, or muting it;
  • Per-app output selectors make it possible to play different apps through different audio devices.
  • The one-click Magic Boost is designed for getting richer, fuller sound from tiny laptop speakers.
  • The 10-band Lagutin equalizer can now be applied to audio from Spotify, Safari, and anything else.
  • You can apply Audio Unit effects to any application or device.
  • You can access all the settings for the Mac’s Output, Input, and Sound Effects devices.
  • Super Volume Keys enable Mac keyboard volume keys to work with HDMI monitors and other digital audio output devices.

Version 4.1 adds Dark Mode support. The app’s menu bar icon can now provide a simplified approximation of the current output volume, and even show when the output device is entirely muted. You can now adjust audio in the Finder, as well as the OS’s “Text to Speech” functionality. The update also includes over 30 other improvements, as well as bug fixes.

SoundSource runs on macOS 10.11 and higher. A free fully-functional trial available for download. While in trial mode, SoundSource’s features will disable after 10 minutes of use. The unrestricted full version can be purchased for $29. Current users of version 3 can upgrade to version 4 for $19.
