Rogue Amoeba SoundSource 4 delivers system-wide audio control

Rogue Amoeba today announced SoundSource 4, a macOS audio utility updated with “massive” new functionality and fully redesigned interface. SoundSource originated as a very basic tool to speed up access to your Mac’s speakers and mics. With SoundSource 4, it’s grown into a powerful system-wide audio utility which offers functionality to help every Mac user. It delivers fast access to all the settings for your Mac’s Output, Input, and Sound Effects audio devices right from your menu bar. Per-app controls let you change the volume of any app relative to others, and send individual apps to different audio outputs. SoundSource 4 can also augment your audio output on the fly, with the powerful “Magic Boost” button, a 10-band Lagutin equalizer, and advanced Audio Unit support.
Rogue Amoeba SoundSource 4 is available now for $29. It requires macOS 10.11 or later. If you own SoundSource 3, you can move to version 4 at a discount. Try it out, then purchase your discounted upgrade for just $19. Finally, folks who purchased SoundSource on or after 1 February 2019 will receive a complimentary upgrade to SoundSource 4.
