What type of mime should i use for mp3

I am trying to decide which type of mime to choose to return mp3 data (submitted php)

according to this listing of mime types: http://www.webmaster-toolkit.com/mime-types.shtml

.mp3 audio/mpeg3 .mp3 audio/x-mpeg-3 .mp3 video/mpeg .mp3 video/x-mpeg

What is the difference between them and which should I use?

It is best to use the RFC defined by mime-type audio/mpeg .

I had a problem with mime types and where tests were run for several file types. It looks like every browser sends a mime type change for a specific file. I tried to download open source php mp3 and zip files that I found:

  • Firefox (mp3): audio / mpeg
  • Firefox (zip): application / zip
  • Chrome (mp3): audio / mp 3
  • Chrome (zip): application / octet-stream
  • Opera (mp3): audio / mp 3
  • Opera (zip): application / octet-stream
  • IE (mp3): audio / mpeg
  • IE (zip): application / x-zip-compression

So, if you need several types of files to download, you should do some tests so that each browser can download the file and pass the mime type check.

Use .mp3 audio/mpeg , which I always used. I think others are just aliases.

You should always use audio / mpeg since firefox cannot play audio / mpeg3 files

standard way to use audio/mpeg , something like this in your PHP header ...

header('Content-Type: audio/mpeg');
