Handling the APEv2 tag Leave feedback

The APE tag is a standard used to add metadata, such as the title, artist, or track number, to digital audio files. The APEv1 tag was designed for the Monkey’s Audio format. In MP3 files, the APE tag was originally stored at the very end of the file, with no inline declaration in the body of the file. But later the standard was extended to add a header, allowing APE tags to be at the beginning of files and allowing metadata values to be Unicode rather than simply ASCII. The improved standard is called APEv2.

The GroupDocs.Metadata API allows reading the APEv2 tag in an MP3 audio.

The following steps show how to read the APEv2 tag in an MP3 file.

1. Load an MP3 file
2. Extract the root metadata package
3. Get the APEv2 tag by using the MP3RootPackage.getApeV2method
4. If the APEv2 tag is not null then check for all of its metadata properties

try (Metadata metadata = new Metadata(Constants.MP3WithApe)) {
	MP3RootPackage root = metadata.getRootPackageGeneric();

	if (root.getApeV2() != null) {
		System.out.println(root.getApeV2().getAlbum());
		System.out.println(root.getApeV2().getTitle());
		System.out.println(root.getApeV2().getArtist());
		System.out.println(root.getApeV2().getComposer());
		System.out.println(root.getApeV2().getCopyright());
		System.out.println(root.getApeV2().getGenre());
		System.out.println(root.getApeV2().getLanguage());

		// ...
	}
}

The GroupDocs.Metadata API supports removing the APEv2 tag from an MP3 audio.

The following are the steps to remove the APEv2 tag from an MP3 file.

1. Load an MP3 file
2. Get the root metadata package
3. Remove the tag by calling the removeApeV2 method
4. Save the changes

advanced_usage.managing_metadata_for_specific_formats.audio.mp3.MP3RemoveApeTag

try (Metadata metadata = new Metadata(Constants.MP3WithApe)) {
	MP3RootPackage root = metadata.getRootPackageGeneric();
	root.removeApeV2();
	metadata.save(Constants.OutputMp3);
}
