About .dff Files
DFF files are a type of digital audio file that store Direct Stream Digital (DSD) sound data.
They capture very high-resolution audio and are often used in recordings like SACDs.
- Main Use Case: Storing high-quality DSD audio for playback and professional audio production.
- Technical Detail: The format may use little-endian byte ordering in version 2.0, as indicated by the MIME type application/octet-stream.
- MIME Types: audio/x-dff shows its primary association with DSD audio. In some contexts, audio/x-dsf is also linked with DSD data.
- Supported Software: Audio players like Foobar2000 (with suitable plugins), JRiver Media Center, and other high-fidelity playback applications can open or convert these files.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
