Audio Normalizer
Audio Normalizer brings uneven audio to a consistent loudness target so your exports match common publishing expectations. Upload an audio file, choose a target preset such as Streaming/Video (-14 LUFS), Podcast (-16 LUFS), Voice/Speech (-19 LUFS), or Broadcast (-23 LUFS), then click Normalize audio to download a normalized MP3. The backend runs a two-pass loudness workflow with FFmpeg’s loudness normalization filter: it first measures Integrated loudness (LUFS), True Peak (dBTP), loudness range, and threshold, then applies the final normalization pass using those measured values for predictable results. The tool also returns the measured input loudness so you can see how far your file was from the selected target. This is useful for creators exporting from different editors, interviews with varying volume, or deliverables where perceived loudness needs to be consistent. An optional AI Assistant can recommend the best preset for your use case, but it only runs when you click and never changes your file automatically.
