Inheritance: java.lang.Object, com.groupdocs.metadata.core.MetadataPackage, com.groupdocs.metadata.core.CustomPackage
public final class MpegAudioPackage extends CustomPackage
Represents MPEG audio metadata.
This example demonstrates how to read MPEG audio metadata from an MP3 file.
try (Metadata metadata = new Metadata(Constants.MP3WithID3V2)) { MP3RootPackage root = metadata.getRootPackageGeneric(); System.out.println(root.getMpegAudioPackage().getBitrate()); System.out.println(root.getMpegAudioPackage().getChannelMode()); System.out.println(root.getMpegAudioPackage().getEmphasis()); System.out.println(root.getMpegAudioPackage().getFrequency()); System.out.println(root.getMpegAudioPackage().getHeaderPosition()); System.out.println(root.getMpegAudioPackage().getLayer()); // … }
