MP3Gain - Audio Normalization
音樂
免費 · App 內購買
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.
Import from anywhere
• Select files from the Files app
• Pull tracks straight from your Music Library
• Open an audio file in MP3Gain from any app
Note: DRM-protected tracks — for example, Apple Music subscription titles — can't be imported or processed.
Supported formats
MP3, FLAC, M4A, WAV, AIFF, and OGG.

評分與評論
- 此App未收到足夠的評分或評論以顯示概況。
• Fixed a crash that could happen after importing a very large number of files — cover art now uses far less memory.
• Temporary files are cleaned up as you go, so long sessions no longer fill up your device's storage.
