Volume Booster: HyperVolume

HyperVolume makes quiet audio you already own genuinely louder - quiet recordings, mumbled voice notes, audiobooks mastered too low - without turning them to mush.

Cranking the gain on a quiet track makes it loud and ugly. HyperVolume rebuilds the signal properly: a compressor lifts the quiet passages, up to +15 dB of gain raises the whole track, and a limiter sits at the end of the chain catching the peaks before they clip. You get volume that stays listenable.

READ THIS BEFORE YOU DOWNLOAD

HyperVolume is a player for audio files you own. You add your files, and it plays them louder.

It cannot boost other apps, and it cannot boost streaming. That means Spotify, Apple Music, YouTube and audiobook apps like Audible. iOS does not let any third-party app touch protected or streaming audio, so no app on the App Store can raise their volume.

What it does play:
- Files you add from Files or iCloud Drive - MP3, M4A, AAC, WAV, AIFF and FLAC, plus M4B audiobooks
- Songs already in your device's music library that aren't DRM-protected, which means your own imports and purchases

If your library is all streaming, this app has nothing to work with.

HEAR IT BEFORE YOU DECIDE

There's a demo built into the app. One clip, boost on, boost off, switch between them as it plays. You'll know in ten seconds whether it does anything for you - no subscription needed.

THE SOUND CONTROLS

Volume - Up to +15 dB on a fader with a real level meter beside it. It reads the actual output signal, so when it runs into amber and red you can see you're pushing it.

Equalizer - Ten bands as vertical faders, the way an EQ is meant to look. Drag a curve by hand or start from one of 22 presets covering Rock, Hip-Hop, Jazz, Classical, Vocal, Podcast and more.

Bass - A low shelf for weight underneath the track, without the boom that swallows everything else.

Reverb - Seven spaces, from Small Room through Hall and Plate to Cathedral, with an amount dial so you can add air rather than drown in it.

A PROPER PLAYER, NOT JUST A SLIDER

- Background playback, so it keeps going when you leave the app
- Lock screen and Control Center controls, including skip
- A queue with shuffle and repeat that survives backgrounding
- Sleep timer that fades out instead of stopping dead
- Album artwork, search and sort across your library
- The phone's own speaker, AirPods, Bluetooth, wired headphones and CarPlay audio

NO ACCOUNT. NO SIGN-UP.

There is no login, because there's nothing to log into. It works offline, and your files stay on your device. Nothing is uploaded, and there's no analytics profile following you around. If you subscribe, the purchase lives on your Apple ID - tap Restore Purchases in Settings on a new device and it comes back.

WHAT PREMIUM INCLUDES

HyperVolume runs on a subscription. You can open the app and look around, and the demo plays without paying, but adding and playing your own files needs Premium:
- The volume boost, with its compressor and limiter
- The ten-band equalizer and all 22 presets
- Bass boost
- Reverb and all seven spaces
- Everything added to Premium later

Premium is available as an auto-renewing subscription. The price and length are shown in the app before you confirm, and payment is charged to your Apple ID. It renews automatically unless you turn off auto-renew at least 24 hours before the period ends. Manage or cancel it any time in your device Settings under your Apple ID. Any unused part of a free trial is forfeited if you buy a subscription.

ONE HONEST NOTE ON LOUDNESS

+15 dB is a lot. Loud music through headphones damages hearing, and that damage doesn't come back. The meter turns amber then red for a reason - treat the top of the range as a warning, not a target.
