Sound Pro is your all in one audio toolkit. Import your own tracks, then boost, equalize and measure sound like a pro. BUILT IN PLAYER WITH REAL BOOST Import songs from Files or your downloads and play them inside Sound Pro. Volume boost and deep bass are applied to your music in real time by a true audio engine, so you hear the difference the moment you move the slider. Please note: iOS keeps every app's audio separate, so Sound Pro processes the music you play inside the app. It cannot change the sound of Spotify, Apple Music or YouTube. 10 BAND EQUALIZER Shape your sound with studio grade precision. Choose from Flat, Bass, Treble, Vocal, Rock and Pop presets, or fine tune all 10 frequency bands yourself and save your own custom preset. REAL TIME DECIBEL METER Measure ambient noise in real time with a precise dB meter. Know instantly whether your environment is Safe, Normal, Caution or Risk level, so you can protect your hearing and stay aware of your surroundings. SLEEP AND EVIDENCE MODES Track noise levels overnight with Sleep Mode, or log timestamped recordings with Evidence Mode for documentation you can share. 8D AUDIO AND NOISE CLEANING Immerse yourself in spatial, surround style audio, or clean up background noise for clearer sound. FREE TO START Boost up to 250 percent, six equalizer presets, the full decibel meter, sleep timer, speaker test and your last three recordings are all free. Pro raises boost to 500 percent and unlocks every preset, custom presets, 8D Audio, Noise Cleaning, Sleep and Evidence modes, calibration and 10 saved recordings. ## Pricing and in-app purchases Base price: Free. **Subscriptions** | Subscription | Price | Period | | --- | --- | --- | | Sound Pro Yearly | $34.99 | per year | | Sound Pro Monthly | $7.99 | per month | | Sound Pro Weekly | $4.99 | per 7 days | ## Is Sound Pro safe?

PLAYS IN THE BACKGROUND Lock the screen or switch apps and your boosted track keeps playing, with play, pause and scrubbing on the lock screen. EASIER TO GET MUSIC IN Try the built in demo track in one tap, pick songs from your Music library, open any audio file from Files, Safari or Mail with "Open in Sound Pro", and jump back to recent tracks. Also: boost settings stay on when you switch tabs, the noise alert shows on screen, and the free trial length always matches what the App Store grants. ### 1.2 — 2026-09-08 Sound Pro now speaks your language.
