CAF to W64 conversion is the process of converting audio stored in Apple Core Audio File (CAF) format into Sony Wave64 (W64) format. This conversion repackages audio data—potentially preserving multichannel, high-resolution, and metadata—so it can be used in workflows or tools that require W64’s extended file-size and channel support.

CAF files typically use the audio/x-caf MIME type and support multiple codecs including AAC and Apple Lossless. W64 files use the audio/w64 MIME type and are designed to store 64-bit wave data, often used in high-end audio production. Both formats support extensive metadata but differ in file size limits and codec flexibility.
The W64 (.W64) format is commonly used for audio. Understanding its characteristics can be helpful when converting to or from other formats like CAF.
While specific technical details aren't available here, W64 files generally serve the purpose of storing audio effectively within their domain.
Convert your CAF audio files to the W64 format quickly and easily using our online CAF to W64 converter. Designed for users who need high-quality audio conversion without installing software, our tool supports seamless transformation from CAF files to W64 format, maintaining excellent sound fidelity.
CAF files are often used on Apple devices and contain compressed or uncompressed audio data, making them versatile for various applications. In contrast, W64 files offer extended file size support and are favored in professional audio environments that require higher bit depths and sample rates. While CAF balances flexibility and compatibility, W64 emphasizes precision and capacity for large, high-resolution audio files.
Keep original sample rate and bit depth when possible to preserve audio fidelity; converting 96/192 kHz files to lower rates loses high-frequency detail.
For long recordings or multichannel projects, use W64 to avoid the 4 GB file-size limit of standard WAV; W64 supports much larger files.
For batch conversions, process files in groups and ensure consistent sample rate/bit depth settings to avoid extra transcoding steps.
Optimal single-file sizes: prefer splitting extremely long sessions into chunks under several gigabytes for easier transfer and editing, though W64 supports very large files.
This converter made switching from CAF to W64 effortless and fast.

Limitation: converting from a compressed codec inside CAF (e.g., AAC) to PCM W64 will produce larger files and won’t restore quality lost to the original lossy compression.
