I want to know the answer to the following question:
What is used to identify the begining of a valid frame of an MP3 header?
All the background I'm provided with is that "This is followed by a bit indicating that this is the MPEG standard and two bits that indicate that layer 3 is used; hence MPEG-1 Audio Layer 3 or MP3.". Is that enough to answer the question?
Answer: yes
