Cranked Spotify to full volume but it’s still not loud enough - especially on a MacBook with its small built-in speakers? macOS caps system audio lower than most people realise, but you can push music well past that ceiling without turning it into a distorted mess.
Why Spotify maxes out too quietly on a Mac
There are two separate volume controls at play, and that trips a lot of people up. Spotify has its own in-app volume slider, and macOS has the system volume. When both are at 100% and the music still sounds thin, you’ve hit the macOS hardware ceiling - the operating system simply won’t send any more level to your speakers or headphones.
A few things make this worse for music specifically. MacBook Air and 13-inch Pro speakers are physically tiny, so they run out of headroom fast. Many tracks are also mastered more quietly than the loud, compressed pop you might be used to, so a jazz record or an acoustic album can feel dramatically quieter at the same setting. And if you listen on AirPods or small Bluetooth speakers, the cap can feel even lower.
Before reaching for an app, it’s worth a 20-second check. Open Spotify’s settings and look at the Volume level option - set it to Loud. Then turn off normalisation if your favourite tracks are quiet, or leave it on if you want every song at a consistent level. That alone recovers some headroom. But if Spotify and macOS are both maxed and it’s still too quiet, you’ve reached the genuine limit of what the OS allows - and that’s where a booster comes in.
How to boost Spotify past the macOS limit
To go louder than the system maximum you need software that amplifies the audio after Spotify hands it to macOS. The catch is that naive amplification clips: push the signal past what the format can hold and you get harsh, crackly distortion that ruins the music. The fix is a limiter - processing that catches peaks before they clip and holds them in check, so you get more loudness without the nasty edges.
This is exactly what Vlume is built for. It boosts your Mac’s system audio up to 800% - eight times - past the OS maximum, and its always-on limiter keeps the boosted sound clean instead of letting it break up. Because it’s built on Apple’s modern Core Audio process-tap API, there’s no kernel extension, no driver, no restart and no admin password: you open it and your music is louder in seconds. It applies to everything, so the same boost works for Spotify, Apple Music, YouTube or any other player.
There’s a free option worth knowing about too. eqMac is open-source and includes a boost-beyond-100% setting, but it installs a kernel-level HAL audio driver (which needs your admin password) and has no limiter, so heavy boosting can distort. Boom 3D is another popular choice with a strong 31-band equaliser and 3D surround, though it’s typically sold through subscription bundles and doesn’t publish a numeric boost figure.

Shape the sound, not just the volume
Loudness is only half the story - the right tone makes music feel bigger even before you push the level. Vlume includes a 6-band equaliser, so you can add a little low-end weight to thin laptop speakers or lift the treble for more sparkle and clarity. A modest bass and presence boost often makes a track feel noticeably louder and fuller without touching the master volume at all.
If you listen through more than one set of speakers, Vlume also supports multi-output with per-device volume - handy for sending Spotify to your desk speakers and a second pair across the room at the same time, each at its own level.

Vlume runs on macOS 14.4 and later as a universal binary for both Apple silicon and Intel Macs. Try Vlume free for three days, no card required, and hear your music the way it’s meant to sound.
