Core Audio Format (CAF) is an advanced audio container developed by Apple, designed to overcome limitations of older formats like AIFF and WAV. It supports high-quality, uncompressed audio with flexible metadata storage, variable bit rates, and extensive codec compatibility. CAF files can handle large audio files efficiently, supporting 32-bit floating-point audio and multiple audio tracks with comprehensive metadata embedding.
Supports large file sizes, advanced metadata, multiple audio tracks, high-resolution audio, flexible codec support. Efficient storage and streaming capabilities. Native integration with Apple platforms. Excellent for preserving audio quality and complex audio projects.
Limited cross-platform compatibility. Requires specific software for full functionality. Less universal compared to MP3 or WAV. Larger file sizes can be challenging for storage and transmission. Minimal support in non-Apple environments.
Primarily used in professional audio production, music recording, sound design for film and video games, podcast production, and Apple ecosystem audio applications. Commonly employed in macOS and iOS audio workflows, digital audio workstations (DAWs), and high-fidelity audio archiving. Preferred for preserving original audio quality in professional media environments.
