40 * @brief This class provides methods to access the audio metadata.
44 * The %AudioMetadata class provides methods to access the audio metadata that contains audio content-specific attributes.
46 * The following example demonstrates how to use the %AudioMetadata class.

52 * #include <FSystem.h>
54 * using namespace Tizen::Content;
57 * MyClass::TestAudioMetadata(void)
59 * Tizen::Base::String contentPath = Tizen::System::Environment::GetMediaPath() + L"Sounds/hot.mp3";
60 * AudioMetadata* pAudioMeta = ContentManagerUtil::GetAudioMetaN(contentPath);
61 * result r = GetLastResult();
63 * pAudioMeta->GetTitle();
64 * pAudioMeta->GetFrequency();
65 * pAudioMeta->GetArtist();
66 * pAudioMeta->GetAlbumName();
67 * pAudioMeta->GetDuration();
68 * pAudioMeta->GetYear();
70 * Tizen::Media::Image image;
71 * r = image.Construct();
73 * Tizen::Graphics::Bitmap* pBitmap = pAudioMeta->GetThumbnailN();
74 * r = GetLastResult();
76 * Tizen::Base::String thumbnailPath = Tizen::System::Environment::GetMediaPath() + L"Images/audio.bmp";
77 * r = image.EncodeToFile(*pBitmap, Tizen::Media::IMG_FORMAT_BMP, thumbnailPath, false);
