C++

public sealed class MpegAudioPackage : CustomPackage

Public NotInheritable Class MpegAudioPackage

The MpegAudioPackage type exposes the following members.

Constructors

	Name	Description
	MpegAudioPackage	Initializes a new instance of the MpegAudioPackage class.

Properties

	Name	Description
	Bitrate	Gets the bitrate.
	ChannelMode	Gets the channel mode.
	Copyright	Gets the copyright bit.
	Count	Gets the number of metadata properties. (Inherited from MetadataPackage.)
	Emphasis	Gets the emphasis.
	Frequency	Gets the frequency.
	HeaderPosition	Gets the header offset.
	IsOriginal	Gets the original bit.
	IsProtected	Gets true if protected.
	Item	Gets the MetadataProperty with the specified name. (Inherited from MetadataPackage.)
	Keys	Gets a collection of the metadata property names. (Inherited from MetadataPackage.)
	KnowPropertyDescriptors	Obsolete. Gets a collection of descriptors that contain information about properties accessible through the GroupDocs.Metadata search engine. (Inherited from MetadataPackage.)
	Layer	Gets the layer description. For an MP3 audio it is '3'.
	MetadataType	Gets the metadata type. (Inherited from MetadataPackage.)
	ModeExtensionBits	Gets the mode extension bits.
	MpegAudioVersion	Gets the MPEG audio version. Can be MPEG-1, MPEG-2 etc.
	PaddingBit	Gets the padding bit.
	PrivateBit	Gets a value indicating whether [private bit].
	PropertyDescriptors	Gets a collection of descriptors that contain information about properties accessible through the GroupDocs.Metadata search engine. (Inherited from MetadataPackage.)

Methods

	Name	Description
	AddProperties	Adds known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well. (Inherited from MetadataPackage.)
	Contains	Determines whether the package contains a metadata property with the specified name. (Inherited from MetadataPackage.)
	Equals	(Inherited from Object.)
	FindProperties	Finds the metadata properties satisfying the specified predicate. The search is recursive so it affects all nested packages as well. (Inherited from MetadataPackage.)
	GetEnumerator	Returns an enumerator that iterates through the collection. (Inherited from MetadataPackage.)
	GetHashCode	(Inherited from Object.)
	GetType	(Inherited from Object.)
	RemoveProperties	Removes metadata properties satisfying the specified predicate. (Inherited from MetadataPackage.)
	Sanitize	Removes writable metadata properties from the package. The operation is recursive so it affects all nested packages as well. (Inherited from MetadataPackage.)
	SetProperties	Sets known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well. This method is a combination of AddProperties(FuncMetadataProperty, Boolean, PropertyValue) and UpdateProperties(FuncMetadataProperty, Boolean, PropertyValue). If an existing property satisfies the predicate its value is updated. If there is a known property missing in the package that satisfies the predicate it is added to the package. (Inherited from MetadataPackage.)
	ToString	(Inherited from Object.)
	UpdateProperties	Updates known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well. (Inherited from MetadataPackage.)

Examples

This example demonstrates how to read MPEG audio metadata from an MP3 file.

using (Metadata metadata = new Metadata(Constants.MP3WithID3V2))
{
    var root = metadata.GetRootPackage<MP3RootPackage>();

    Console.WriteLine(root.MpegAudioPackage.Bitrate);
    Console.WriteLine(root.MpegAudioPackage.ChannelMode);
    Console.WriteLine(root.MpegAudioPackage.Emphasis);
    Console.WriteLine(root.MpegAudioPackage.Frequency);
    Console.WriteLine(root.MpegAudioPackage.HeaderPosition);
    Console.WriteLine(root.MpegAudioPackage.Layer);

    // ...
}
