Hey, we have some other technologies to use... like Bluetooth or wi-fi.. even IR... Transmission of information using sound is stone age...

Thanks for crushing my dreams of winning 10 btcs by holding my phone up to the speaker of my favorite classic rock station bro.

At first i thought this was about performing transactions using audio to transport the transaction request for the first time, for things like a blind client in a mobile that doesn't got a fresh blockchain, only the private key of an address that was expected to have money (so you could for example use a cheap(er) device that doesn't got an internet connection, walk to a vending machine, press a couple buttons and place the device against the mic of the vending machine, and the vending machine would relay the transaction to the internet); i'm not quite sure now....

You could send the private key for a wallet. That, or a mtgox voucher would probably be the most efficient method.

like dialup? that would work, it transfers data like any other type, just really slow, slower than 56k so like 10-30 seconds per block or more even.

If it has to be audible, the max bitrate is about 3~4Kbps IIRC. Or 0.5KB/s, no idea how large is a bitcoin send/receive packet though.

the more garbled the sound gets, the longer it will take to reliably send. on dialup you only get 56k on a good day, and your hooked directly up to the line. but its not much text so it may only take like 1-2 seconds to get. but i dont see why it would not work, thats pretty much just like dial up, changing data into sound, then changing the sound into data on the other end. that's how this and dial up work.

Actually I dont know what I'm thinking. Not like dialup though. What if a radio station wanted to give out 10 free bitcions at some point during the day. You'd have to be waiting with your smartphone up to the speaker to hear the garbled mess they send through. Once your phone picks up the garbled mess it decodes it and you get your bitcoins.

Not sure if something like that would work with blockchains and what nots. Just an thought.

you mean hold your device close to a terminal and it plays a sound it picks up? i could see that working.

Yep exactly like that. Maybe you could even transfer them through lan lines like that I dont know. lol

I was wondering if there would be a way to transmit bitcoins by sound. I know you can send and recieve by scanning QR codes but it seems like that could easily be converted to sound.

I guess it would sound like a 300 baud modem. Also I'm not sure what real world purpose this would have. Just wondering if its been talked about.
