SD file extension - Entropic sound data format

What is sd file? How to open sd files?

File type specification:

Audio and sound file type icon Audio and sound file type

sd file icon: sd filetype icon

The sd file extension seems to be mainly related to various audio formats, including the Entropic sound data format.

Entropic Research Laboratories used a proprietary file format for its WAVES+ display program, ESPS signal processing library and the HTK hidden Markov model speech recognition toolkit. WAVES+ and ESPS were withdrawn when Entropic was acquired by Microsoft in October 1999.

This sd file type entry was marked as obsolete and no longer supported file format.

This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.
