Audio Loudness Analyzer
Audio Loudness Analyzer measures how loud your audio actually sounds, using loudness standards designed for real listening rather than simple peak meters. Upload an audio file and run a server-side loudness pass to get Integrated loudness in LUFS, True Peak in dBTP, Loudness Range (LRA), and the total duration. These measurements are useful when you are preparing a podcast episode, music preview, video voiceover, or broadcast-style deliverable and want consistent playback volume across platforms. The tool also shows a quick target comparison for common use cases, so you can see whether your file is likely to be normalized up or down and whether true-peak headroom may be an issue after encoding. For users who want actionable guidance, an optional AI Assistant can recommend a sensible loudness target and true-peak ceiling for the selected use case and explain why, while keeping AI processing entirely on the backend.

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.
