- Description
- 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.
- 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.
