SD files contain a sound record called Sound Designer, and are therefore classified as Audio Files.
This software was widely used in the past (90s) to edit sounds in Apple Mac OS operating systems.
SD files are compatible with applications on Apple MacOS and Microsoft Windows.
SD files are also created and used by Entropic Research Laboratories for the WAVES + visualization program, the ESPS signal processing library, and the HTK speech recognition toolkit, and although they are of a different format than Sound Designer, they are still being audio files.
In this application, SD files are used for speech recognition research, although it has been used for numerous other applications. HTK is basically a set of libraries that can be used in Web applications, originally developed at the University of Cambridge, and later acquired by Entropic Research Laboratory Inc., and finally, Microsoft bought Entropic.
In any case, the libraries are free to use and therefore are in use at hundreds of sites worldwide.
