The official MIME-type is: audio/vnd.wave

See: https://en.wikipedia.org/wiki/WAV and https://tools.ietf.org/html/rfc2361

Seems we also need to change video/x-msvideo to video/vnd.avi

[Borewit]

You are right!

@Borewit @sindresorhus sorry for coming late in the discussion, but I have to say that audio/vnd.wave and video/vnd.avi are not official mime types, but instead should be used audio/wav and video/avi, and I tell you why.

Firstly, the RFC you mentioned (RFC 2361), is not a standard rfc, but instead an informational rfc, that does not represent an Internet community consensus or recommendation.

Secondly, as far as I know, mime types are only used on the web and by browsers to render the content. So, it's logical, to use mime types that browsers know. In my experience with audio files, audio/vnd.wave isn't recognized by any major web browser (google chrome, mozilla firefox, safari), but audio/wav is.

I have a strong opinion that there isn't an official mime type for .wav and .api files, but in the years emerged an convention to use audio/wav and video/avi. If it's not, I will gladly change my opinion.

Here a more long discussion I had on this subject (at the end of the comment I correct myself): patrickmccallum/mimetype-io#18 (comment)

Some sources I have used:

• RFC statuses - https://www.ietf.org/standards/process/informational-vs-experimental/
• RFC 2361 - https://tools.ietf.org/html/rfc2361
• MDN web docs - https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types/Common_types

[sindresorhus]

I agree. Practical usage trumps technical specifications in web development. If audio/wav and video/avi work across major browsers and audio/vnd.wave and video/vnd.avi don't, it's clear which MIME types should be used. PR welcome.

Ok, I will gladly do the pull request.
