As technological limitations gradually lifted, composers were given more freedom and, with the advent of CD-ROM, pre-recorded soundtracks came to dominate, resulting in a noticeable shift in composition and voicing style. Popular early CD-ROM titles were released with high-resolution graphics and recorded music. Since the audio was not reliant on a sound-card's synthesis, CD-ROM technology ensured that composers and sound designers could know what audio would sound like on most consumer configurations and could also record sound effects, live instruments, vocals, and in-game dialogue.
