Convert ExtAudioFileRef type to AudioFileID type in iOS

Question

I am using ExtAudioFile services and I want to use an AudioFile service that requires the AudioFileID parameter. This parameter corresponds to the ExtAudioFileRef used in ExtAudioFile services. How to convert from type ExtAudioFileRef to type AudioFileID?

Answer 1

Just make it up, it works great! AudioFileID audiofile = (AudioFileID)AudioExt where AudioExt is of type ExtAudioFileRef

Answer 2

I know this old one also answered, but I just noticed it and thought that I would leave the correct answer here for future reference

AudioFileID audioFile;
UInt32 dataSize = sizeof(AudioFileID);
ExtAudioFileGetProperty(extAudioFile, kExtAudioFileProperty_AudioFile, &dataSize, &audioFile);
