A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .fev Files
FEV files are binary files used for storing FMOD Audio Events.
They contain event data that guides when and how sounds play in games and multimedia applications.
The file follows the MIME type application/octet-stream, meaning the data is stored in a raw binary format for efficient handling.
These files work with audio middleware like FMOD Studio, which is common in game development and interactive media.
- Main use case: Storing interactive audio event definitions.
- Other uses: Integrating sound effects into games and multimedia projects.
- Software: Opened and edited by FMOD Studio and related tools.
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.

FAQs
What is a .fev file?
A .fev file is an FMOD Audio Event file used primarily in video game development. It contains the logic and definitions for sound events (such as footstep timing or engine revving) but does not usually store the actual audio waveform itself. These files are generated by FMOD Designer or legacy versions of FMOD Studio.
How do I open a .fev file?
You can open or import these files using FMOD Designer (legacy) or FMOD Studio. Since these are developer files, standard media players like VLC or Windows Media Player cannot open them. If you are trying to extract audio from a game, you often need a specific tool like FSB Extractor to handle the associated bank files instead.
Can I convert a .fev file to MP3 or WAV?
No, you cannot directly convert a .fev file to MP3 or WAV because it does not contain audio data. It only contains the instructions for how to play sounds. The actual audio is typically stored in a companion .fsb (FMOD Sample Bank) file, which is the file you would need to convert to listen to the music or sound effects.
What is the relationship between .fev and .fsb files?
These two file types usually work together as a pair in game audio engines. The .fev file acts as the "brain," containing the event hierarchy and parameters, while the .fsb file acts as the "storage," containing the actual compressed audio samples. Without the .fsb file, the .fev file has no sounds to trigger.
Why does my computer identify the .fev file as a generic binary file?
The operating system identifies .fev files with the generic MIME type application/octet-stream because they are raw binary data specific to the FMOD engine. They do not have a standardized text or media header that Windows or macOS recognizes natively without the specific FMOD software installed.
How do I fix a missing .fev file error in a game?
If a game crashes with a "missing .fev file" error, it means the audio engine cannot load the sound definitions required to run. To fix this, try verifying the integrity of the game files through your launcher (like Steam or Epic Games) or reinstalling the application to ensure all data assets are present.
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.
