Which MIME types are related to file extension ".dff"?
The .dff file extension is associated with 3 MIME types:
audio/x-dff, audio/x-dsf, application/octet-stream.
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
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.
Associated MIME types

FAQs
How do I open a DFF file on my computer?
You need a high-fidelity audio player such as Foobar2000 (with the SACD input plugin), JRiver Media Center, or Audirvana. Standard media players usually cannot decode the Direct Stream Digital (DSD) data found in DFF files without specific codecs.
What is the difference between DFF and DSF files?
While both formats store DSD audio, DSF files support embedded metadata tags (like album art and artist names), whereas DFF files typically do not. Many audiophiles convert DFF to DSF to better organize their music libraries.
How can I convert DFF to FLAC?
You can use audio conversion tools like dBPoweramp, XLD (on Mac), or Foobar2000's converter component. Converting DFF to FLAC changes the audio from a 1-bit DSD stream to multi-bit PCM, making it compatible with more devices.
Why can't I edit the metadata tags in my DFF files?
The DFF file structure does not natively support standard ID3 tagging mechanisms used in MP3 or FLAC files. To store metadata like song titles and cover art directly inside the file, it is recommended to convert the file to the .dsf format.
Can I play DFF files on Android or iPhone?
Yes, but you need specialized apps like USB Audio Player PRO, Neutron Music Player, or Onkyo HF Player. For the best quality, users often connect an external USB DAC that supports native DSD decoding.
What MIME type should be used for DFF files?
The specific MIME type is usually audio/x-dff. If a server is not configured for high-resolution audio, it might serve the file as application/octet-stream. You can verify configuration details on mime-type.com.
General 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.
