I think this is a useful article but I'm not sure the author understands the distinction between a podcast and audio recordings generally. To be clear, a podcast is a set of audio recordings in an open format (typically MP3) distributed though open content syndication (typically RSS). If it's just some audio files you send to students, it's not a podcast (especially if there are access controls, proprietary formats, or subscription limitations built in). So I think this article should be titled 'Using Audio Recordings in Your Classroom'. Ah, but then it's content for 2008, not 2021. What would have made it more current? For one thing, perhaps, instead of asking whether the audio meets accessibility standards, the author could have suggested some best practices for things like AI-supported automated transcription.
