Handling metadata in WAV files

Reading audio details

The GroupDocs.Metadata API supports extracting technical audio information from WAV files.

The following are the steps to read audio details.

  1. Load a WAV audio
  2. Get the root metadata package
  3. Extract  the native metadata package using the WavRootPackage.getWavPackage method
  4. Read the WAV audio properties

try (Metadata metadata = new Metadata(Constants.InputWav)) {
	WavRootPackage root = metadata.getRootPackageGeneric();
	if (root.getWavPackage() != null) {
		System.out.println(root.getWavPackage().getAudioFormat());
		System.out.println(root.getWavPackage().getBitsPerSample());
		System.out.println(root.getWavPackage().getBlockAlign());
		System.out.println(root.getWavPackage().getByteRate());
		System.out.println(root.getWavPackage().getNumberOfChannels());
		System.out.println(root.getWavPackage().getSampleRate());
	}
}
