Nero Deck
A recording deck for the EUPHONIA.
It records your sets in lossless stereo, streams them live, and runs digital vinyl, all from one SD image and a wooden faceplate.
You spent four thousand on the mixer. Capturing what comes out of it shouldn't mean a laptop wobbling on a flight case. Nero Deck archives every set in lossless stereo and puts it one link from your audience, with nothing extra on the table.

Everything it does.
Recording
Multi-hour stereo capture over full-duplex USB. The archival WAV stays untouched while a compressed, limited copy renders offline beside it. A live skip counter on the deck tells you the take is clean before you've even finished playing.
Live streaming
Cloudflare Tunnel is built in, so your set is reachable at stream.yourname.com with no port-forwarding and no static IP. WebRTC monitoring on the LAN turns your phone into the headphone preview.
Vinyl + digital hybrid
Serato CV02 timecode decoded on the Pi (xwax-derived). Any digital file plays at vinyl pitch from a control record, routed per-channel through the EUPHONIA's phono inputs. A beat-quantised loop engine feeds the LINE inputs as its own channel.
Music intelligence
Live key detection on a 30-second rolling buffer, Camelot-coded for harmonic mixing. Live BPM alongside it. Both sit on the deck in real time as you play.
Bluetooth bridge
Pi to A2DP speakers or headphones out, phone to EUPHONIA in. Both pairings are managed from the deck's settings, with no desktop and no fuss.
Boot + reliability
Plymouth splash to kiosk UI in about two seconds, with no terminal flash in between. Realtime scheduling holds the audio thread, and the code is audited for path traversal, RT-safe keylock and concurrency.
Where your listeners tune in.
A public page anyone can open in a browser. No app and no account, just the live stream.

Built for one mixer.
Nero Deck is tuned to the EUPHONIA: its USB audio behaviour, its phono stages, its four channels. It won't run a DJM or a Xone, and that's deliberate.
