recorded with additional instruments. Also,  all of the films gunshot sounds had been replaced with newly created gunshot  sound effects. Also, the audio in the films final sequence in Tony Montanas  mansion was completely revamped deleting some sound effects that were  previously incorrectly placed, also Tonys lines during the gunfight were  easier to hear and some of the henchmen had alternate "groans" dubbed in. The  biggest change of all in the sound was from Tonys machine gun/grenade  launcher ("Say hello to my LITTLE FRIEND!") which was given a loud, rocket  launcher style sound effect. As mentioned above, the 20th anniversary DVD  only has a 5.1 and DTS track of the original mix.
