- 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.
- A CDDA (CD Digital Audio File) is a type of audio file extracted directly from an audio CD. This format is also known as CD-DA, which stands for Compact Disc Digital Audio. It is a standard format for audio CDs established by Philips and Sony in the Red Book specification. CDDA files represent uncompressed digital audio data in a linear PCM (Pulse Code Modulation) format.
