Boom 3D is a capable app, but if all you really want is your Mac to get genuinely louder without distorting - and you'd rather not sign up for a subscription bundle to get it - there's a simpler option. Here's an honest look at where Boom 3D shines, and where a focused alternative like Vlume fits better.
What Boom 3D does well - and where it might be overkill
Boom 3D earns its reputation. It ships a detailed 31-band equaliser, 3D/surround effects, and a polished interface, so it's a strong pick if you love tweaking a rich sound profile or want spatial-style audio for headphones. That breadth is the point.
The trade-offs are price and focus. Boom 3D is paid and is often sold through subscription bundles, and it doesn't publish a numeric boost figure - so if your single goal is "make this quiet video louder," you may be paying for surround processing and a 31-band EQ you'll never touch. For a lot of people, the real need is just clean extra loudness for movies, calls, and music. If that's you, a tool built around that one job tends to be easier to live with.
What "clean loudness" actually requires
Pushing audio past the macOS maximum is the easy part. Doing it without turning quiet dialogue into a crackly mess is the hard part. Two things matter most.
- A real ceiling on the boost. Vlume boosts macOS system audio up to 800% (8×) past the OS maximum - a defined, documented amount rather than an open-ended gain slider.
- An always-on limiter. This is the piece that keeps loud audio clean. As you push the volume up, Vlume's limiter catches the peaks so the sound gets dramatically louder while avoiding the clipping and distortion that ruin heavy boosting.

No driver, no admin password, no subscription
This is where a modern, focused app really separates itself. Vlume is built on Apple's current Core Audio process-tap API, so there's no kernel extension, no audio driver, no restart, and no admin password. You download it, open it, and it works - nothing buries itself in your system.
Pricing is just as simple. Vlume is a one-time £39 Pro licence (1-2 Macs) or £59 Family (up to 5 Macs) - no recurring fee and free updates. That's the core appeal for anyone leaving Boom 3D specifically to escape a subscription.
And you don't give up everything in return for the simplicity. Vlume still includes a 6-band equaliser for shaping the sound and multi-speaker (multi-output) support with per-device volume, so you can play through several outputs at once. It's a smaller EQ than Boom 3D's 31 bands by design - enough to fix thin or boomy audio without turning tuning into a hobby.
So which should you choose?
If you genuinely want surround effects and granular 31-band control, Boom 3D is a reasonable fit and worth its price for that use. But if your priority is clean maximum loudness with zero driver friction and a one-time cost, that's exactly what Vlume is built for. Vlume runs on macOS 14.4 or later as a universal binary (Apple silicon and Intel).

Worth noting: eqMac is a free, open-source option with its own "boost beyond 100%," but it installs a kernel-level audio driver (which needs your admin password) and has no limiter, so heavy boosting can distort - if that's your concern, our eqMac alternative guide covers it.
