Remove Audio Metadata on Windows

Clean supported audio tags without confusing metadata removal with changing the recording or deleting all embedded content.

Short answer

Select a supported MP3, FLAC, WAV or M4A file in File Explorer and choose Clean Metadata, then Create clean copy. Read File details and play the output. Lyrics, comments, artwork and information needed for playback can remain; the recording itself is not edited.

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. Choose a small sample

    Start with one recording. Close software that is writing tags or changing the file. A supported filename extension alone does not prove its internal encoding is supported.

  2. Create a clean copy

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

  3. Read what changed

    Open File details and check removed metadata fields and any retained information. Metadata such as supported title or artist tags may be removed; this is not a selective tag editor.

  4. Listen and inspect

    Play the reported output and check its duration and playback. Inspect tags in your usual player. Review lyrics, comments and artwork separately because authored content and supported playback information can be preserved.

  5. Use the intended file

    Keep the original for your library if you need its tags. Share the inspected output rather than accidentally selecting the original. If there was nothing removable, a new copy may not have been created.

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

Use the specific File details explanation. Unknown chunks, unsupported profiles or damaged data may prevent safe processing. Export a separate supported copy from the original app if appropriate, check playback and retry.

Changing .aac to .m4a does not convert a file. Standalone AAC is not an admitted file extension in this release.
