Make Audio Files Play at a More Consistent Volume

In Just Converter’s Quick Tools, open Media tools and Audio tools. Enable Loudness normalization and use the same LUFS target for the recordings. Convert separate copies, then compare them at one player volume.

Before you start

  • Just Converter 1.2.5 or later and two or more recordings to compare.
  • Any loudness target specified by your publisher or receiving service.

Follow these steps

  1. Start with one recording

    Open Media tools → Audio tools and choose Add media. Add one recording and choose the audio output format you need. Leave the trim fields empty to process the whole file.

  2. Enable loudness normalization

    Select Loudness normalization. LUFS sets the overall listening level; dBTP limits the highest true peaks. If you have no required target, start by testing the app defaults of −16 LUFS and −1.5 dBTP.

    1. Enable Loudness normalization, then set its two targets.
  3. Convert a separate copy

    Choose an Output folder. Select Start operation, review the job and choose Confirm and start. The app first measures the audio, then applies the result in a second pass; let both finish.

    Just Converter reports the normalized Blackbird recording as successful.
    Open the saved recording before applying the settings to more files. Enlarge image.
  4. Use the same target for the other files

    Once the sample sounds suitable, apply the same normalization values to the other recordings and convert them. Keep each original so you can compare or change the settings.

  5. Compare at one player volume

    Play parts of each output without moving the player’s volume control. Listen for large jumps between files, distortion and background noise before using the set.

Check your result

  • The files play at a more consistent level at the same player volume.
  • Speech or music remains clear, and you checked every file’s result.
If you need more help

If your publisher specifies a target

Use the publisher’s LUFS and true-peak requirements. The app defaults are a starting point for a listening test, not a guarantee that a particular service will accept the file.

If a louder copy exposes noise or distortion

Raising a quiet recording can make its background noise more noticeable. Normalization cannot reconstruct peaks already distorted in the source. Use a cleaner recording or edit the audio before converting.

If one speaker is much quieter within the same recording

A shared loudness target helps compare whole files. It does not provide separate controls for each speaker. For large changes within a recording, use an audio editor with clip-level or compression controls, then check the edited file.
