The d file extension is most likely best known for its use in D programming language. Its focus is on combining the power and high performance of C and C++ with the programmer productivity of modern languages like Ruby and Python. Special attention is given to the needs of quality assurance, documentation, management, portability and reliability.
The D language is statically typed and compiles directly to machine code. It's multiparadigm, supporting many programming styles: imperative, object oriented, and metaprogramming. It's a member of the C syntax family, and its appearance is very similar to that of C++.
The d file represents the default source code written in D programming language.
Use text editor, or source code editor to open *.d source code files.
Unless there is some kind of parser available, a direct conversion to other languages will be hard.

Record marked as obsolete and not updated for a long time.
SPPACK audio appears to have been a specialized format for storing audio or speech data. The format is associated with AT&T Bell Laboratories and may have served a specific speech or audio-processing purpose.
SPPACK and its .d files are obsolete and are no longer in active use. Documentation and software capable of reading the format are difficult to find.
Some audio editors may still be capable of playing SPPACK audio. If the original SPPACK software is available, it may be required to read or play the .d file.
Modern audio editors are unlikely to open this obsolete format directly.
No reliable, generally available converter for SPPACK audio is known. If compatible software can open the file, conversion may be possible by exporting the audio to a current format.
