there was no "feature that you [could not] see on the screen and touch and play with". LoPiccolo composed the game's score—called "dark", "electronic" and "cyberpunk" by the Boston Herald—on a Macintosh computer and inexpensive synthesizer, using Audio Vision. It dynamically changes according to the player's actions, a decision made in keeping with the team's focus on emergent gameplay. Each track was "written at three different intensity levels", which change depending on the player's nearness to enemies; and certain events, such as victory in combat, trigger special music. The game's tracks were composed of four-bar segments that could be rearranged dynamically in reaction to game events, with "melodies through-composed on top". LoPiccolo noted that, when using this method, it is necessary to write music that "still flows with the overall theme and doesn't jump around". Because the score was closely tied to the gameplay, LoPiccolo had to work closely with Church and Rob Fermier, the latter of whom wrote the "interactive scoring module" that allowed for dynamic music. After recording the music, LoPiccolo recorded all of the game's sound effects. He later recalled visiting an automobile repair shop with "portable recorder and a mic", and "having [his] mechanic [...] hit things with wrenches and so forth, just to get the raw material". He developed the game's audio over 16 months, working on a contractual basis until Tribe disbanded in May 1994; Ned Lerner gave him a full-time job as audio director the next day. Tim Ries composed the "Elevator" music. The original September 1994 floppy disk release of System Shock had no support for spoken dialogue. The enhanced CD-ROM was released in December 1994, which featured full speech for logs and e-mails, multiple display resolutions, and more detailed graphics. The CD-ROM version is often considered to be superior to the floppy version. After completing work on the sound and music for the floppy version, LoPiccolo recorded all of the spoken dialogue for the CD release, using company employees and his friends' voices, which he mixed with ambient sounds to create "audio vignettes". Doug Church later said, "We tried to keep them from shipping the floppy version and instead just ship the CD version, but Origin would have none of it". System Shock producer Warren Spector later expressed regret concerning the floppy version, stating, "I wish I could go back and make the decision not to ship the floppy version months
