- 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.
- Compressed audio file similar to an .MP3 file, but offers several performance improvements; examples include a higher coding efficiency for both stationary and transient signals, a simpler filterbank, and better handling of frequencies above 16 kHz; maintains quality nearly indistinguishable from the original audio source.
