What is MIME type "audio/mpa"?

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

The MIME type audio/mpa labels files encoded with the MPEG Audio standard. It mostly covers MPEG Audio Layer II but can also refer to MPEG Audio Layer I content.
It tells software and systems which decoder to use.

This MIME type is common in digital audio broadcasting and online streaming. It is also used in professional audio storage and playback.
It serves to reduce file size while preserving sound quality.

Files using this type include those with the MPA, MP2, MP1, and M1A extensions.

For more detailed technical information, see MPEG-1 Audio on Wikipedia.

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.
