Short answer

Right-click an MP3, FLAC, WAV or supported M4A file in File Explorer and choose Clean Metadata, then Create clean copy. Read the file's result and play the copy. Supported title or artist tags may be removed, but speech, lyrics, comments and artwork can remain.

This guide covers Clean Metadata. Check requirements and download options before you begin.

Before you start

  • Clean Metadata with an active license on Windows 11 24H2 or later, x64.
  • A sample MP3, FLAC, WAV or M4A on a local NTFS drive.
  • A player for checking the output and a backup of any tags or library organization you want to keep.

Start here

  1. Pick one recording

    Choose a sample and close any app that is changing it or its tags. Keep the original if its titles, artist names or other tags help organize your library.

  2. Create a clean copy

    In File Explorer, right-click the file, open Clean Metadata and choose Create clean copy. Leave the source in place until the run finishes.

  3. Read what changed

    Read the Removed metadata fields count and any retained-field notes beside the filename. The count is not a list of removed tags. Clean Metadata is not a tag editor for choosing a new title or artist.

  4. Play the copy

    Open the reported output in your usual player. Check the duration and sound, then inspect tags such as title and artist in the player's file information. Review lyrics, comments and artwork separately because these can be kept.

  5. Choose the file to share

    Send the output you checked. If the app found nothing removable, it may not have created a new copy; follow the result instead of looking for a file that was never saved.

Check your result

  • The recording plays and has the expected duration.
  • The relevant tags and all retained-field notes were checked.
  • Any personal information in speech, lyrics, comments or artwork was reviewed separately.
Playback data is not the same as personal tags

For example, a broadcast WAV time reference can be retained to preserve synchronization. Its originator, calendar date and descriptive history are handled separately.

Supported lyrics, comments and cover images can be preserved as authored content. Metadata cleaning does not mute speech, remove an audible name or guarantee that all embedded text disappears.

If the audio cannot be processed

Read the message beside the filename first. Some audio encodings or damaged files cannot be processed. If appropriate, export a separate supported copy from the original app, check playback, then try again.

Standalone AAC files are not supported in this release. Renaming .aac to .m4a does not convert the recording.
