Music preservation technology
Audio Codecs are Comms chips which connect any device with a larger Æthernet connection to the larger infosphere to download music from thousands of years and millions of archives. Audio Codecs work on a peer-to-peer network, trawling the various Æthernets in search for audio files in the public domain or which have been marked to be added. They coordinate to repair old music and bring them up to modern standards of fidelity, and when introduced to a new Æthernet, such as one on an abandoned world, they will share their newly found music with the larger network at first opportunity to keep the music alive. They were invented by Anthem and are a must-have for music aficionados.
