"The Gear I worked on music and sound design for id Software during the last year and a half of the game's development. During the first few months, I experimented with defining this new antimusic we were set on using. Doom³'s score would feature no traditional instruments except for a bit of piano and choir. Otherwise the entire score is purely electronic in nature. My sounds were built from various sources, including the FS1R and CS6X from Yamaha, Korg's M1, WaveStation and X5DR synths, an Emu Audity 2000 and an Alesis DMPro on the hardware side. In software, sources included countless sample libraries running on two GigaStudio machines, Native Instruments' Reaktor, Absynth, and Vokator, Atmosphere from Spectrasonics, and many custom recorded and designed sounds. Everything was recorded into Cakewalk SONAR in real time one part at a time, with no sequencing. Occasionally an ambient bed would first be assembled in Sony Acid. The resulting looping sections would then be imported into SONAR for beautification. Mixes were exported from SONAR to Sony Sound Forge for mastering, downsampling to 22 kHz, and conversion to Ogg Vorbis format."
