CRI HCA is a proprietary compressed audio format developed by CRI Middleware for use in video games and multimedia applications. It is designed for efficient streaming and playback of audio within CRI's ADX2/CRIWARE game audio middleware. The format is widely used in Japanese console and mobile games to store music and sound effects.
RealPlayer created RA for audio streaming. It makes use of various audio codecs from those that deliver high-fidelity sounds to those that record low bitrate audio data. Radio stations mainly used it for online streaming, but current formats have overthrown it.
