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.
