Apologies for not introducing myself in the audio! I struggled a bit to take on this topic at a high enough level to keep it to about a half hour, because every subtopic is nuanced and the details are always technical.

Not sure how well it worked out but my intention was to focus mainly on the 2 most common examples - hiding messages in text and in images.

Topics I mentioned:

encryption vs steganography

who uses steganography and for what purpose?

hiding text in text

hiding data in images using LSB encoding

hiding data in other places

steganalysis

If you want to leave feedback, consider saying whether you think it would be more useful to talk about:

using the most popular tools and software

detailed look at specific steganographic techniques

case studies

in the unlikely case that I do a followup episode (I doubt there's a strong interest in this topic)
