The short version
"Boom 3D alternatives" covers two different searches wearing the same words. Most people typing it want their Mac to sound bigger or louder, which is squarely an equaliser and volume-boost job. A smaller group actually has a routing complaint, a call that plays through the wrong speaker, an output that will not switch, and they only landed on Boom 3D because it was the first audio app that came up. This page is written for both, and it will tell you plainly which apps below are real substitutes and which one is not.

Going through the options
SoundSource
SoundSource, from Rogue Amoeba, is the closest thing to a like-for-like Boom 3D replacement here. It has a full equaliser, audio effects and Audio Unit plugin support, so you can build a real processing chain over your Mac's sound. It also groups outputs and handles apps individually, which Boom 3D does not do at all. It costs $49, or $25 to upgrade from an earlier version, and it is the more capable app of the paid options if you want the full toolkit.
FineTune
FineTune is free and open source, with a 10-band equaliser, 20 presets, AutoEQ headphone correction and volume boost up to 4x, which puts it closest to Boom 3D's actual job at no cost. The catch is the system requirement: it needs macOS 15 Sequoia or later, so it is not an option if your Mac is on an older version. It also does multi-device output, though that is not its main focus.
Sound Control
Sound Control, from Static Z Software, is free to download with a subscription for full features, $1.99 a month or $14.99 a year. It has per-app volume and mute plus a 10 or 31-band equaliser with Audio Units support, so the equaliser side is covered. We could not confirm a dedicated volume-boost or 3D feature, and output grouping is not what it is built around.
Chorus
Chorus has no equaliser, no audio effects and no volume-boosting feature of any kind, so if you came here wanting your Mac to sound bigger or louder, it is not the app. What it does instead is group several outputs to play as one with a single real volume, route individual apps to different devices, and switch between saved setups with a keyboard shortcut. We are including it here only because some "Boom 3D alternatives" searches turn out to be routing complaints in disguise. If yours is not one of them, pick from the three above.
Every feature free for 30 days. No account, no card details.
Download for MacSo which should you pick?
Want a real equaliser and a fuller toolkit, plugins and all? SoundSource. Want the same job done for free, and your Mac is on macOS 15 or later? FineTune. Fine with an equaliser on a subscription? Sound Control.
Realise your actual problem was never about loudness or EQ, but about getting the right sound to the right speaker or the right app? Chorus, honestly, is a different tool for a different job. It costs $4.99 once, and 30 days free tells you quickly whether that was the problem all along.

Frequently asked questions
Is Chorus a good alternative to Boom 3D?
Not for what Boom 3D actually does. Boom 3D's job is boosting volume and adding a 3D surround effect, and Chorus has neither feature at all. Chorus is only worth considering if your real need turns out to be different: grouping several outputs to play as one, or sending individual apps to different devices. If louder or bigger sound is the goal, look at SoundSource, FineTune or Sound Control instead.
What does Boom 3D actually do?
Boom 3D, from Global Delight, is a volume booster and equaliser for Mac. It offers a 10 or 31-band equaliser with presets, a 3D surround-sound effect, and basic per-app volume control. It is free to download, with a Lifetime Base Pack at $49.99 and a Lifetime Discount Pack at $19.99 as in-app purchases, prices checked August 2026.
Which Boom 3D alternative has a free equaliser?
FineTune. It is free and open source, with a 10-band equaliser, 20 presets, AutoEQ headphone correction, and volume boost up to 4x. The trade-off is that it needs macOS 15 Sequoia or later, so it is not an option on older Macs.
Does Chorus have an equaliser or a volume boost?
No. Chorus has no equaliser, no audio effects and no volume-boosting feature of any kind. It groups outputs, handles per-app routing, and switches setups with a keyboard shortcut. If shaping or boosting the sound is what you need, Chorus is the wrong tool.
What is the best paid alternative to Boom 3D?
SoundSource, from Rogue Amoeba. It is $49, or $25 to upgrade from an earlier version, and pairs a full equaliser with Audio Unit plugin support, effects and output grouping. It is the more complete toolkit of the paid options here.
