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.
NIST Sphere waveform audio
Through our analysis of SPH files, we know that one use of the format is NIST Sphere waveform audio. We have not yet described in detail what these files contain and what they are used for, but our team is working tiredlessly through thousands of file formats. We'd love hearing from you if you have information about the format.
SPH file openers, viewers, etc.
These apps are known to open certain types of SPH files. Remember, different programs may use SPH files for different purposes, so you may need to try out a few of them to be able to open your specific file.
