Unison USB™. This refers to our new USB interface that Mike and team have been prototyping for the last year, and in beta on for the last three months or so. Sounds pretty boring in a world where you can talk to the air and have Alexa play your favorite house mix for you? Yeah, well, enjoy your compressed Bluetooth sound over a walkie-talkie speaker, and the paranoia of wondering if Jeff Bezos is listening to you take a dump. Instead, we’ll concentrate on solving the problem of getting great audio over a general-purpose interface using a general-purpose microprocessor and our own single-minded code. Which actually turned out to be quite a challenge. Which also ended up working so well that Mike now prefers it over SPDIF. Yes. Mike. No, no alien pods have been found decomposing near his house. Maybe the reason it works so well is that it’s designed to do one thing and one thing only: transfer PCM digital audio from a source and convert it to I2S. That’s it. No 500x DSD, no MQA, no Brutoof, no shamalamadingdong, no 32/768 or 64/1536, no unicorn formats period.
