- Description
- id RoQ is a proprietary video (and audio) container format developed for use in video games. It uses a custom codec combining vector quantization for video and a simple compression scheme for audio, designed for fast decoding on limited hardware. It was used in several id Software games such as Quake III Arena and Return to Castle Wolfenstein to play full-motion video cutscenes.
- Digital audio format based on Apple's Core Audio technology; stores audio data as well as text annotations, markers, channel layouts, and other information; similar to an .AIFF or .WAVE file, but does not have a 4GB size limit and can store any number of audio channels.
