SoundSource includes several powerful audio effects to help you improve the sound of your audio. We’ve worked to make these built-in effects simple to use, so anyone can get great-sounding audio.
When you activate Magic Boost, you’ll get richer, fuller sound from any source. Magic Boost actively listens ahead several milliseconds for quieter passages of audio to give them a boost, while keeping louder audio from being overdriven. Whatever your audio source, Magic Boost will give you tremendous volume, all with a single click.
Magic Boost is available on both the system’s default output device and on individual applications. This makes it possible to use Magic Boost to improve the sound of your entire system, or just for specific apps.
For over two decades, Rogue Amoeba’s renowned 10-band Lagutin equalizer has helped users get better sound.
From the EQ’s inline view, you can select from almost two dozen presets to improve your audio in an instant.
For more control, click to reveal the full popover. From here, you can configure the EQ bands and preamp gain manually.
Once you’ve found the right sound, you can even save your own custom equalizer settings. Adjust the equalizer to your liking, then select Save Preset As… from the Presets menu.
For full details on Presets, see the Presets section of our Effects Overview page.
SoundSource includes an effect for adjusting the stereo balance of audio, which can toggle between Balance and Pan modes.
The Balance effect adjusts the relative levels of audio between the left and right stereo channels. This is useful for correcting audio that is skewed to one side, or for compensating for hearing loss in one ear.
The Pan adjustment acts in a different fashion, setting the position of audio between the left and right stereo channels. This can be helpful when placing audio in a specific location within the stereo field.
This effect can be applied to individual app sources, as well as the system output.
Headphone EQ provides automatic calibrated equalization for headphones, powered by the well-known AutoEq project. Use it when playing audio to headphones to make them sound their very best.
Profiles are available for thousands of different headphone models. Select the appropriate model to apply audio adjustment tuned precisely to get the best out of your exact headphones.
It’s also possible to manually load custom EQ profiles into the Headphone EQ effect. For full details, see this support article.
While Magic Boost will increase the level of quiet portions of audio, Volume Overdrive can assist in getting extra volume out of your speakers overall. It’s limited to individual applications, and can drive up their volume to 400%, making it possible to hear your audio even in loud environments.
Volume Overdrive improves the quality of overdriven audio, with limiting to prevent digital distortion. This works very well to amplify quiet audio, without blowing out sound that’s already loud. This does mean that when you’re listening to louder audio, you may not notice much boost when using Volume Overdrive.
