The other point which I had heard before was that the original SW mix was started and don't have a sense of the percentage completed by Sam Shaw and his team (Robert Rutledge, Gordon Davison, Gene Corso and six others) before the reigns were handed over to Burtt. They were hired to do the complete mix, but Ben's ingenuity eventually showed that to capture the right 'feel' Burtt's sound collection would be given greater importance. Shaw having worked in the industry before brought in previously 'canned' sound effects, a package called 'Edit-Rite'. The book goes into some of their contributions but quickly mentions how it was tweaked by Burtt. Shaw's team with constant feedback from Burtt finished the stereo mix, after that Burtt alone handled the monaural and foreign mixes. (pgs 35-41)
