What is MIME type "audio/vnd.nuera.ecelp4800"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

audio/vnd.nuera.ecelp4800 marks files that hold voice data compressed with the Nuera ECELP4800 codec. This codec is designed to reduce file size while keeping speech understandable even on low-bandwidth systems.

Purpose: Encodes speech for efficient transmission and storage in systems like telephony and mobile communications.
Functionality: Compresses human voice using a specialized algorithm focused on clarity at low bitrates.
Use cases: Ideal for real-time voice messaging, mobile network communications, and any environment where bandwidth is at a premium.

Files bearing this format typically use the ECELEP4800 extension.

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 are multiple MIME types listed for one extension?

Different applications and historical conventions may use alternative MIME identifiers for the same kind of file. Showing them all helps ensure compatibility across systems.
