audioOut · output

Terminal stereo output. Two mono inputs (L, R) routed to the host AudioContext destination. Optional output-device dropdown via setSinkId (Chromium 110+).

The terminal stereo output — where the patch reaches your speakers. It takes two mono inputs (L and R), each routed to one side of the stereo bus, following the Eurorack convention that every cable is mono and you patch both sides for stereo. Mental model: the last module in the chain; whatever you wire into L and R is what you hear. Two always-on safety stages sit between your signal and the hardware: a 5 Hz DC-blocking high-pass (inaudible, but it stops slow DC drift from a feedback loop or a misrouted LFO from stressing your speakers) and a master brickwall limiter with a -1 dBFS ceiling. The limiter looks ahead 2 ms, so anything that stays under the ceiling passes through at exactly unity — it does not compress, colour or pump your low end — and anything above it is turned down by just enough to reach the ceiling, which is what stops a runaway patch clipping the device. The card also lets you choose the output device on browsers that support it. There are no outputs — this is a sink.

`L`	audio	Left-channel audio to the speakers. Patch a mono source here for the left side; for a stereo source wire both L and R. audio signal
`R`	audio	Right-channel audio to the speakers. Leave it unpatched for a mono signal in L, or wire the right side of a stereo source here. audio signal

controls

control	what it does
Master	Master output level applied to both channels before the limiter, 0 (silence) to 1 (unity), default 0.7. It sets your overall loudness; the limiter downstream is a brickwall ceiling that does nothing at all until you exceed -1 dBFS, so use this for the actual mix level rather than driving into the limiter for loudness.
