VOX to CAF conversion is the process of transforming audio encoded in the VOX format (often ADPCM or Dialogic ADPCM used for telephony recordings) into the Core Audio Format (CAF), Apple’s flexible container for high-quality audio. This conversion rewraps or decodes the VOX data into CAF with selectable sample rates, channels, and codecs so the audio becomes compatible with modern macOS/iOS tools and professional audio workflows.

VOX files generally use the Dialogic ADPCM codec and have the MIME type audio/vox, commonly used in telephony systems. CAF files have the MIME type audio/x-caf and serve as a flexible container supporting multiple codecs like AAC, ALAC, and PCM. CAF is widely used for high-quality audio recordings on Apple platforms and professional audio editing.
The CAF (.CAF) format is commonly used for audio. Understanding its characteristics can be helpful when converting to or from other formats like VOX.
While specific technical details aren't available here, CAF files generally serve the purpose of storing audio effectively within their domain.

VOX files are typically low-bitrate audio recordings used in telephony systems, while CAF files are versatile, high-quality audio containers preferred in professional audio environments. Unlike VOX, CAF supports multiple codecs and larger file sizes, offering better flexibility and quality. Converting VOX to CAF enables improved compatibility and expanded editing capabilities.
Keep VOX file sizes modest: telephony VOX files are usually small (under 10 MB); for long recordings split into segments under 100 MB to simplify processing.
Preserve quality by converting VOX to CAF with Linear PCM or ALAC rather than re-encoding to lossy codecs; upsample only when necessary to avoid artifacts.
For batch conversion, use tools or scripts that preserve original timestamps and filenames; verify a few samples before processing large batches.
Format-specific limitation: VOX is typically low sample-rate, mono, and ADPCM-compressed—expect limited fidelity and limited metadata compared with modern formats.
