answer: sound quality are excellent
paragraph_question: question: How is audio?, context: About a month ago I bought a Samsung UN75F7100 3D LED TV set. About 2 weeks ago I bought an OPPO BDP-103 3D Blu-Ray player on Amazon. Of course, I didn't have any 3D Blu-Ray disks to play so I bought Avatar. Wow! If you got the equipment to play this you gotta' get it. Picture and sound quality are excellent and the 3D is only as good as a movie originally shot in 3D could be. I'm afraid that any other move shot in 2D and processed up to 3D will not stand up to this one. Oh. By the way. I thought the movie was great! Hope there will be a sequel. (In 3D of course.) 
sentence: Picture and sound quality are excellent and the 3D is only as good as a movie originally shot in 3D could be.
