Playing Audio from Tag?
Look, I know that a chip can store around 500 Bytes, and that the smallest possible 2 minute mp3 file is around 500 Kilobytes, which is 1024 times what an NFC tag can store. This obviously makes NFC tags impossible to use as a storage medium for audio files using conventional means. That being said, I'm interested if anyone knows any sort of hack or workaround for storing audio files on NFC tags. For example, LEGO has been using NFC bricks to store audio files by making their custom NFC reader have an onboard synthesizer which is capable of producing the desired sounds from simple text instructions on the NFC chip. Obviously this requires custom hardware, but it's fun.
My unrealistic goal would be to have a 2 minute voice recording stored on the chip, so that a mobile phone could download it off of the chip without an internet connection. Not needing internet is vital to this. I could obviously link to an audio file stored on an online content distribution service, but that's boring. I'd also like to generally avoid custom hardware or software, so that anyone can access the audio file without needing anything they don't already possess. This isn't that vital though.
Just how close could one reasonably get to this goal?
