 Along with the digital effects , Spielberg wanted the film to be the first with digital sound . He funded the creation of DTS , which would allow audiences to " really hear the movie the way it was intended to be heard " . The sound effects crew , supervised by George Lucas , were finished by the end of April . Sound designer Gary Rydstrom considered it a fun process , given the film had all kinds of noise – animal sounds , rain , gunshots , car crashes – and at times no music . During the process , Spielberg would take the weekends to fly from Poland to Paris , where he would meet Rydstrom to see the sound progress . Jurassic Park was finally completed on May 28 , 1993 .
