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.
A WAV file is an audio file that uses a standard digital audio file format utilized for storing waveform data. It allows audio recordings to be saved with different sampling rates and bitrates and is often saved in a 44.1 KHz, 16-bit, stereo format, which is the standard format used for CD audio.
