MP3Gain vs Volume Booster・Bass & EQ

Make all your audio the same volume — without touching the volume dial. Ever jump from one song to the next and grab for the volume button? Or finish a podcast that's twice as loud as the one before? MP3Gain fixes that. It measures the true loudness of your audio and applies exactly the right amount of gain, so everything you listen to, share, or upload sounds even and professional. Quick for everyday fixes. Precise for creators. Three measurement modes cover every job: • Peak — match tracks to a target peak level (in dB). • RMS — match the average energy of your tracks for consistent perceived volume. • EBU R128 (LUFS) — the international loudness standard used by streaming and broadcast platforms, with true-peak limiting. Built-in presets Start in one tap with presets tuned to real-world targets, and save your own for repeat jobs. • Music — RMS -20 dB • Podcast — EBU R128 -16 LUFS • Voice — EBU R128 -18 LUFS • Streaming Video — EBU R128 -14 LUFS • Default — EBU R128 -23 LUFS Batch processing Import a whole album, playlist, or batch of files and normalize them all at once. Adjust one file and apply the same settings to every file in your list. Progress is shown per file, and you can cancel anytime. Hear it before you export Play the original and the processed version side by side in the app, so you know it sounds right before you save or share it. Keep your music intact MP3Gain preserves embedded album art and metadata. Lossy formats keep their original bitrate; lossless files are processed without additional lossy compression.

Some files are just too quiet. Volume Booster plays them much louder — a meeting recording, a lecture, a film with whispered dialogue — without the crackle that usually comes with turning things up. Your phone was already at maximum. HOW IT WORKS Import an audio or video file from Files. It opens at its original volume. Drag the boost up until it sounds right. A limiter stays on the whole way, so louder never turns into distorted. LOUDER HERE, NOT EVERYWHERE iOS does not let apps raise the phone's system volume. The boost applies to audio played inside this app, on the files you import — other apps are unaffected. Better to know that now than after you install. SHAPE THE SOUND • Bass boost for thin, distant recordings • EQ presets for speech, for music, and for quiet late-night listening • A custom equalizer you set band by band • Boost, bass and tone are remembered per file, so a track opens the way you left it WHILE YOU LISTEN • Background playback and lock-screen controls • Skip back and forward, or scrub anywhere in the file • A sleep timer that fades out and pauses • Rename, share or delete anything in your library WHAT IS FREE Importing and playing, background listening, lock-screen controls, bass, and the always-on limiter — at every level, for everyone. Pro raises the boost ceiling, lifts the library limit, unlocks every EQ preset, the custom equalizer and the sleep timer, and removes ads. IT STAYS ON THIS PHONE No account, no sign-up, nothing uploaded. Files you import are copied to your device and stay there.
