When you're live or recording, you have to hear everything clearly the moment it happens - a guest's voice in your headset, the music bed under your intro, a co-host on Discord, the game you're reacting to. If your Mac's audio is too quiet to monitor confidently, here's how to fix it without adding noise or distortion.
Why monitoring audio gets quiet on a Mac
Content creation stacks a lot of sound on top of one another. You're often listening to a call app, a soundboard, a browser tab and your own DAW or stream software at the same time - and each one has its own level. macOS then caps the master output at a fixed maximum that, on MacBook speakers or many USB headsets, simply isn't loud enough to ride those sources confidently. The result is that you turn everything to 100%, it's still too quiet, and you end up guessing whether a guest actually dropped out or you just couldn't hear them.
The honest fix isn't to crank a single app - it's to lift the whole system output past the OS ceiling, then keep it clean so nothing clips in your ears. That's a different job from a per-app slider, and it's exactly the gap a system-wide booster fills.
Boost and monitor system audio cleanly
Vlume sits across your entire Mac's output and lifts it up to 800% (8x) past the macOS maximum, so every source you're monitoring - call, soundboard, game, music - comes up together. The part that matters for live work is the always-on limiter: it catches peaks before they distort, so when a guest suddenly gets loud or a sting hits, your headphones stay clean instead of crackling. You get headroom and confidence without the harshness that usually comes from pushing volume hard.
Because Vlume is built on Apple's modern Core Audio process-tap API, there's no kernel extension, no audio driver to install, no restart and no admin password. That's genuinely useful for creators: you're not adding a fragile virtual device into a setup you've already dialled in, and there's nothing extra that can break mid-stream after a macOS update. It runs natively on Apple silicon and Intel (macOS 14.4+).
Vlume is for monitoring and playback - making what reaches your ears and your speakers louder and cleaner. It isn't a routing or capture tool, so for sending audio into OBS or recording it into your DAW you'll still use your usual capture setup. Think of it as the layer that makes sure you can actually hear everything you're working with.
Shape the sound, not just the volume
Loud isn't the whole story - clarity is. Vlume's 6-band equaliser lets you lift the mids so a quiet guest or a muddy interview is easier to follow while you're live, or tame harsh highs from a bright microphone feed so long sessions are less fatiguing.

And if calls are your weak spot, our guide to fixing low Mac volume on Zoom and Teams covers the same monitoring problem from a meetings angle.
Multi-speaker support is handy too: you can send boosted audio to more than one output with per-device volume - for example, your monitoring headphones plus desk speakers - each set to its own level.
How it compares for creators
If you've used Boom 3D, you'll know its 31-band equaliser and 3D/surround effects well; it's a strong tool, though it's typically sold via subscription bundles and doesn't publish a numeric boost figure. eqMac is free and open-source and offers a "boost beyond 100%" option, but it installs a kernel-level HAL audio driver (which needs your admin password) and has no limiter - so heavy boosting can distort, the last thing you want in a live monitor. Vlume's pitch is narrower and creator-friendly: a clear 8x boost, a limiter that keeps it clean, and a driverless install. For a fuller breakdown, read Boom 3D vs eqMac vs Vlume.
Pricing is a one-time £39 Pro (1-2 Macs) or £59 Family (up to 5 Macs) - no subscription. Try Vlume free for 3 days, no card required, and hear your whole setup the next time you go live.
