How do I convert SPH to ALAC?

Upload your SPH file, choose ALAC as the output, and hit Convert. The service decodes SPH's PCM or mu-law audio and wraps it in ALAC (with an .m4a container). After conversion, download the result and add it to iTunes or any Apple device.

How does the conversion handle audio attributes like sample rate and bit depth?

The conversion preserves the original sample rate, bit depth, and channel layout of the SPH file. If the SPH file contains PCM audio, it is losslessly encoded into ALAC. However, if the SPH file uses a lossy codec (like G.711 mu-law), that compression is retained—converting to ALAC won't recover lost quality. Metadata such as recording duration and channel info is transferred, but SPH-specific fields like utterance labels may be set as custom tags in the resulting M4A file.
