yStream is a demonstration station for an AI radio project. It is a real 24/7 music station - Hebrew and international, spanning recordings from 1904 to this year - and there is nobody in the studio. Every track is analysed before it airs: tempo, key, energy, genre, where the vocal starts, and the exact sample where the intro ends and the outro begins to fade. A scheduler writes each hour as an authored timeline rather than a shuffle - rotation, era and genre spread, artist separation, top-of-hour identification. Every segue is executed in samples: a hard cut, a cut with a tail, or a true fade, each crossing at its own point. An AI voice reads over the intro of the song that is actually playing, timed to land before the vocal starts. The music is licensed commercial recordings; no audio here is AI-generated. On air continuously since 13 July 2026. Everything is explained at https://ystream.live Runs unattended on yStream Studio, radio automation with an AI DJ: ystream.live/studio
