Audio Mime-Type

The mime-type is a two-part identifier for file formats transmitted over the internet. For an MP3 file, it's audio/mpeg for example.

Why do we test it?

Proper MIME-type detection ensures that the browser can correctly identify and play the audio in the ad. If the MIME-type is incorrect or missing, it may cause compatibility issues, where the audio fails to play, diminishing the ad's effectiveness.
