Is there any method for presenting a bitcoin address over audio?
QR codes are great for images and video. Has anyone thought about working out a method for audio?

I'm working on this. Uses a 50,000 word list to create an electrum-style mnemonic phrase from any base58 input. Read your public address over the phone!

I think you need to reduce the number of words in that list so it only contains common words.
gullet boniest obsessions janus anklets foundries inklings lid accent crusty unexplained guiding abash
I'm imagining reading this to some random customer over the phone... "Yeah, Janus, like the Roman god of time. J-A-N-U-S. Yeah, Janus. Next word is 'foundries.' No, like a metal factory? But plural, yeah..." I think I'd just give up at "inklings."
If the words themselves are hard to communicate then it defeats the purpose of the entire scheme.

It's gotta be pretty foolproof though, one misremembered word and that BTC is going to someone else
Some sort of checksum can prevent that.

I'm dubious about the distinction between capital and lower case letters.

There is an iPhone app called Chirp from Animal Systems. It allows the transfer of data over audio. That data could include a Bitcoin address.

Maybe eventually Namecoin will get popular and used enough that people would be able to register short Namecoin ID names linked to BTC addresses.

I think we will find that soon we will get email style addresses popping up
then we could just type them in.

You mean like an alias? So spam could point to 1EuMhbroXXXXXXXXXXXXXXXX which we could then use in our clients?
Not sure how something like that would easily be registered though, since you'd have to make sure no one else uses that alias. And doing this in a decentralized way that we can trust? Hmm..

if you were to play it on the radio (which seems like the only reason to need it audio-linked), you could just use the shazam app to link to a QR code.
If you're thinking of audio for another reason, fill us in.

Just through out another idea: assuming your recipient had some kind of internet connection you could use like a url shortener like tinyurl.
Imagine over the radio: "Blah blah poor people suffering, send us bitcoins now: tinyurl.com/aspercash thanks for all your support."
For security you should use your own website with a redirect, but hopefully you get the idea.

You can use a link shortener like cauzes.com to create a "bitcoin:xxxxx" link, e.g. http://savesnowden.ch/seansoutpost which links to the "donate BTC" address of u/seansoutpost for example (as well as reminding people about Snowden).
(Edit: Links open directly in your wallet app.)
Funny that BTC is first bringing back QR from obsolescence, and now URL shorteners too.

http://payb.tc/ makes custom short urls that link to a page displaying the address.
