This is my BIP idea: a fast, robust, and standardized for representing Bitcoin addresses over audio. It takes the binary representation of the Bitcoin address (little endian), chops that up into 4 or 2 bit chunks (depending on type, 2 bit only for low quality audio like american telephone lines), and generates a tone based upon that value. This started because I wanted an easy way to donate to podcasts that I listen to, and having a Shazam-esque app (or a media player with this capability) that gives me an address automatically would be wonderful for both the consumer and producer. Comes with error correction built into the protocol

You can see the full specification of the BIP on my GitHub page (https://github.com/Dako300/BIP-0153).
