I'd like to embed an audio recording in an email or landing page. I know you can do this with videos via YouTube (among other services), but what about just an audio recording?
In an email? No. You can't embed multimedia objects in an email.
In a landing page? Sure. You have to present it in a few different formats for browser compatibility -- Google is your friend on this -- but all browsers can play audio. Or you can use an audio hosting service that will provide its own player that does the format switching for you (SoundCloud, etc.).
You can certainly put a link to it and use an image of a playback there.
