Audio Saving On whatsapp available?

[Pranshul Sood]

Hey guys. My whatsapp is fully updated. Today i noticed something. A friend of mine sent me an audio recording on WhatsApp. Normally we could only listen to the recording in the chats of WhatsApp on our Windows phone, But when i was randomly browsing through my Phone Music collection, I saw a file with a weird staring with AUD... and somethung went on.
Can anyone confirm if the same is happening to them too.
