Loudness LUFS Calculator

Summary

Enter your current loudness and pick a streaming platform to get the exact gain adjustment needed to hit its loudness target.

How it works

1. Enter your track's current integrated loudness in LUFS (measured with a metering plugin or DAW).
2. Select a target streaming platform from the dropdown, or enter a custom LUFS target.
3. The calculator computes the difference between your current level and the platform target.
4. The required gain adjustment in dB is displayed, along with a plain-language recommendation.
5. A clipping warning appears if applying the gain would push your peaks above 0 dBFS.
6. Use the result to adjust your master fader or apply a trim gain in your DAW before export.

Use cases

• Match a podcast episode to Spotify's -14 LUFS target without re-recording.
• Check whether a music master needs gain reduction before uploading to YouTube.
• Quickly compare loudness targets across multiple platforms in one view.
• Teach audio students why streaming platforms normalize loudness and by how much.
• Validate that a mastered track is already within a platform's acceptable loudness window.
• Calculate gain trim for voiceover files before submitting to an audiobook distributor.
