Throughout the 1990s, CRI gradually transitioned its focus, evolving into a provider of audio middleware tools like ADX and Sofdec.

CRI ADX is a streamed audio format which allows for multiple audio streams, seamless looping and continuous playback (allowing two or more files to be crossfaded or played in sequence) with low, predictable CPU usage.

It is essentially a repackaging of MPEG-1/MPEG-2 video with CRI's proprietary ADX codec for audio playback.

CRI Clipper is an automated lip-syncing program which analyzes waveforms and outputs an appropriate lip pattern into a text file, for later substitution into the facial animations of the (in-game) speaker.

CRI ROFS is a file management system for handling a virtual disc image, an extension of the CD-ROM standard.
