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 "The Fraunhofer Gesellschaft owns many of the basic patents underlying these formats as well, with others held by Dolby Labs, Sony, Thomson Consumer Electronics, and AT&T.". Is that enough to answer the question?
Answer: no
