About audio element

Question

I have a question, if I want to add only one audio type, do I write <audio src="example.mp3" type="audio/mpeg"> or do I type <audio src="example.mp3">, is the type attribute needed? Or do I only use it when I add more than one audio types using the <source> element?

Answer 1

Karak10 Type isn't necessary, look at this:
