How do I convert an ALAC file to SPHERE?

Upload your ALAC file to LetsConvert, select SPHERE as the output format (choose NIST SPHERE preset if available), click Convert, then download the resulting .sph file. The conversion runs entirely in your browser or server, so no software installation is needed.

Why would I need to convert ALAC to SPHERE?

SPHERE is widely used in speech corpora (e.g., TIMIT) and by research tools like Praat or HTK. ALAC is common in Apple ecosystems but lacks broad support in speech analysis pipelines. Converting SPHERE ensures lossless PCM audio that these tools can read directly.

How does the conversion handle audio quality and metadata?

ALAC is a lossless codec, and SPHERE often stores uncompressed PCM, so all audio data—sample rate, bit depth, channels—is preserved without loss. However, metadata like album art, tags, and cover images may be dropped because SPHERE's header primarily stores audio encoding parameters. If your SPHERE file uses mu-law encoding, we re-encode to PCM to maintain compatibility.

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