One of the most under-used features of Mastodon is audio. You can attach audio files to your posts, they can be in MP3, OGG, WAV, FLAC, AAC, M4A or 3GP formats. They can be any length, as long as the file size is under 40 megabytes (some servers may have even higher limits).

I've attached an example audio file to this post, you should be able to play it on most interfaces and apps.
