Following GetMetaDataL() function illustrates how to read meta data entries from the audio file. As shown with the function it requires a CMdaAudioPlayerUtility (could also be CMdaAudioRecorderUtility) which also needs to be fully opened with the file, see Audio playing example to see how to open a audio file with CMdaAudioPlayerUtility.

With this example only Title, Album, Artist and Genre entries are retrieved, for information on the other metadata entry IDs you could have a look into the MmfMeta.h header.


#include <MmfMeta.h>
void GetMetaDataL(TDes& aTitle,TDes& aAlbum,TDes& aArtist,TDes& aGenre,CMdaAudioPlayerUtility& aUtility)
TInt MDNumEntries(0);
for ( TInt i(0); i < MDNumEntries; ++i )
CMMFMetaDataEntry* entry(NULL);
TRAPD(error, entry = aUtility.GetMetaDataEntryL(i));
if (error == KErrNone)
if (entry->Name().CompareF(KMMFMetaEntrySongTitle) == KErrNone)
else if (entry->Name().CompareF(KMMFMetaEntryAlbum) == KErrNone)
else if (entry->Name().CompareF(KMMFMetaEntryArtist) == KErrNone)
else if (entry->Name().CompareF(KMMFMetaEntryGenre) == KErrNone)
