How do I convert CAF to SOU with LetsConvert?

Upload your CAF file, select SOU as the output format, and choose the IMA ADPCM compression level. Click 'Convert' to instantly download your SOU audio. Our tool preserves the original sample rate and channel configuration.

Why convert CAF to SOU instead of keeping the original CAF file?

CAF is Apple's high-fidelity audio container, but it's not recognized by legacy game engines and older embedded systems. SOU is a lightweight ADPCM format designed for retro games, offering smaller file sizes and direct hardware compatibility without losing essential audio characteristics like sample rate and stereo balance.

What happens to audio quality and metadata when converting from CAF to SOU?

The converter re-encodes the audio stream using IMA ADPCM, which is lossy and will reduce bit depth (usually from 16-bit or 24-bit to 4-bit per sample). Sample rate and channel mapping are kept intact. Metadata such as track titles, album art, and Apple-specific markers are not retained in SOU, as the format only stores raw audio data.

Is CAF-TO-SOU free to use?

Yes, CAF-TO-SOU on LetsConvert is 100% free with no registration or hidden fees required.

Are my uploaded files safe and secure?

Yes! File privacy and security are guaranteed. Basic conversions run locally in your browser. Files sent for server processing are automatically deleted within 1 hour.

Does this converter work on mobile phones and tablets?

Yes! CAF-TO-SOU works seamlessly across iPhone, Android, iPad, Mac, Windows, and Linux browsers without installing any app.

Is there any software installation required?

No software or browser extension installation is needed. All conversions are performed directly online.
