How to open SPH files

Did your computer fail to open a SPH file? We explain what SPH files are and recommend software that we know can open or convert your files.

What is a SPH file?

SPH files are NIST Sphere waveform audio files, which you can read more about below.

The SPH file extension indicates to your device which app can open the file. However, different apps may use the same file extension for different types of data. So a SPH opener may not be able to open all kinds of SPH files. In this case, though, we only know of one specific use.
