Help!! Any Way to Access Voice Memo?

[situee]

I want to access audios in voice memo.
Is there any way like UIImagePickerController picking images from photo library?

Summary:
After a long time search, I believe there is no usual way to do this.
We can only use iPod Access Library to playback songs, but cannot get the filesystem data.

I check the "iPod Library Access Programming Guide"
Can I use the " Media Item Picker " MPMediaPickerController?
