Okay, here's an example for an MP3 audio file, formatted similarly to your previous examples:

This is an example of an MP3 audio file I found on a website offering royalty-free music. An MP3 is a common audio format that uses compression to reduce file size while maintaining reasonable audio quality. This MP3 file was downloaded from the website and is included here. The website stated that the music is offered under a "Royalty-Free" license, which typically means it can be used in various projects without needing to pay royalties for each use. However, attribution might still be required depending on the specific terms. I will credit and link to the source based on the information provided.
