I have updated the GitHub a lot (changed tones to be less chirpy, fixed some smalls) and made a couple of samples (see attachment for MP3 and FLAC of both tone tables, first 16 then 4). Is this good enough to warrant an official BIP number? I haven't built a decoder yet, but it seems like the encoder is working properly (looked at Audacity, seems like it is working), and some people on reddit want to "allow for decoding experiments"

What suggestions do you all have for it?

It wouldn't be feasible in the vast majority of cases, but I can't think of a reason why it can't be built into the standard.

Would it be feasible to transmit an entire BIP21 URI as audio? If you were to encode any extra information (such as amount), it would be useful to include a checksum for the entire message. This checksum could possibly be used instead of the checksum in the address.

Daniel,
   Thanks for proposing this.  I think this could have some useful use cases as you state.  I was wondering what you would think to adding some additional tones to optionally denote an amount (in satoshis?).

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).
