Another use for the audio would be for watches that can listen but can't use a camera (ie: Samsung S2), so sound would be great.

NOTE:

Addresses aren't really meant to be broadcast - you should probably be encoding BIP32 public seeds, not addresses.  

OR simply:

- Send btc to rick@q32.com
- TXT record _btc.rick.q32.com is queried (_<coin-code>.<name>.<domain>)
- DNS-SEC validation is required
- TXT record contains addr:[<bip32-pub-seed>]

Then you can just say, in the podcast, "Send your bitcoin donations to rick@q32.com".   And you can link it to your email address, if your provider lets you set up a TXT record.   (By structuring the TXT record that way, many existing email providers will support the standard without having to change anything.)

This works with audio, video, web and other publishing formats... and very little infrastructure change is needed.

Have you considered CDMA?  This has the nice property that it just sounds like noise.  The codes would take longer to send, but you could send multiple bits at once and have the codes orthogonal.
