AUDIO Video Interleave to CAF conversion is the process of transforming a video file stored in the AVI (Audio Video Interleave) container into Apple's CAF (Core Audio Format) container or a CAF-wrapped audio stream. This conversion extracts or repackages audio (and if needed, associated metadata) from an AVI file into CAF while preserving sample rates, channels, and compression settings where possible for compatibility with macOS, iOS, and professional audio workflows.

The AVI file typically uses the MIME type video/x-msvideo and supports multiple codecs like DivX and Xvid for video and MP3 or PCM for audio. CAF files use the audio/x-caf MIME type and can contain various audio codecs including Apple Lossless, AAC, and PCM. CAF is widely used in professional audio editing and Apple device ecosystems due to its extensibility and efficient storage.
The CAF (.CAF) format is commonly used for video. Understanding its characteristics can be helpful when converting to or from other formats like AUDIO Video Interleave.
While specific technical details aren't available here, CAF files generally serve the purpose of storing video effectively within their domain.

AUDIO Video Interleave (AVI) is a multimedia container primarily focused on video playback with accompanying audio, commonly used in Windows environments. In contrast, CAF (Core Audio Format) is an audio container developed by Apple, optimized for high-fidelity audio storage and editing. While AVI handles video and audio together, CAF is specialized for audio-only applications with better codec flexibility.
Keep individual AVI files under 1GB for faster uploads and processing; ideal working files are 50–500MB for quick conversions.
To preserve audio quality, export CAF as uncompressed PCM or ALAC rather than lossy codecs; match the source sample rate and bit depth when possible.
For large batches, use a desktop converter or a command-line tool that supports queueing and presets to maintain consistent settings.
Be aware that AVI is a container that may include multiple audio streams or codecs; if the AVI audio codec is unsupported, transcode the audio to PCM or AAC before wrapping in CAF.
This converter made extracting audio from AVI simple and fast.
