Thank you for the response. DSound is all audio, so they use IPFS to store the audio, then their frontend runs some script from what I can see from page source. It looks like SoundCloud.

What I mean is, I can embed an image in a post by simply using the {![] () } formatting.. or just drag a YouTube URL into Steemit/eSteem and it will auto-embed. I wish there was something like that for audio like mp3 or wav.

I see, <audio> tag should be easy to add, but majority of Steem apps disable it for security reasons. Because you can potentially hijack script inside audio tag. But unified audio player embed would be good to have, from what you said, dsound is doing just that with soundcloud audio player.

Ah, makes sense. Thanks.
