I want to know the answer to the following question:
AAC, mp3PRO and MP2 are all members of the same technological family as which other lossy format?
All the background I'm provided with is that "Among these, mp3PRO, AAC, and MP2 are all members of the same technological family as MP3 and depend on roughly similar psychoacoustic models.". Is that enough to answer the question?
Answer: yes
