As much as I talk about image descriptions, which yes, are very, very important, I'd also like to bring some light to describing audio posts. This is just as important as describing your images. There are people who aren't able to access your audio posts for any number of reasons. Yes, audio can sometimes be difficult to describe, just as images can I'm sure, but at least trying is good. There are many, many people on the fediverse who appreciate that immensely.
