How CAF turns into WAV: timed-stream transcoding
The waveform and channel layout inside CAF is decoded first, then re-encoded into WAV's own codec and container profile. Duration typically holds steady even as compression, channel mapping, frame cadence, or auxiliary streams shift underneath it. Core Audio Format input derives sample description, packet table, channel layout, edit information, and data extent from independent CAF chunks. WAV delivery writes a RIFF waveform whose PCM precision, rate, channels, channel mask, peaks, and large file size matter more than codec branding.
Decoded from Apple Core Audio Format chunks designed for long recordings and varied audio codecs. Encoded to a waveform container written here as uncompressed 16-bit PCM audio.

Reading CAF correctly and satisfying what WAV expects
What can fail when CAF audio format is interpreted
Non-Apple applications may reject CAF or support only a subset of the codecs and channel layouts it can contain.
What Waveform Audio cannot safely promise
PCM WAV can be much larger than delivery audio, and converting high-bit-depth material to 16-bit changes sample precision.
How the WAV writer handles this route
The verified WAV profile writes 16-bit little-endian PCM rather than a perceptual delivery codec.
Checking the WAV result before you trust it
Record the CAF evidence before conversion
Inspect the actual codec, sample rate, bit depth, channel layout, duration, markers, and destination-app playback.
Test the WAV file in its receiving workflow
Compare duration, sample rate, 16-bit depth, channels, peaks, and audible clipping.
The delivery decision for this CAF to WAV route
Confirm the receiving player, editor, or publishing service actually names WAV's container and codecs before switching; stay with CAF if extra tracks or original encoding need to survive intact.
What changes between the CAF model and the WAV deliverable
- The source stores Apple Core Audio Format chunks designed for long recordings and varied audio codecs; the destination stores a waveform container written here as uncompressed 16-bit PCM audio. Compare application metadata after that structural change.
- Treat CAF-specific metadata fields as optional in the WAV result until you have actually confirmed they survived.
