Output Audio HTTP

How it fits

Typical backends

Caveats

• I/O contractRaw PCM modes emit headerless interleaved samples, so the client must already know the rate and channel count, whereas container modes emit a complete file per frame. When the upstream sends a list, each frame is delivered as its own message on every active channel in order, and an empty list delivers nothing.
• Parameter interactionbit_rate is honoured only by lossy encoders; sample_rate zero keeps the source rate (opus always encodes at 48 kHz) and channels zero keeps the source layout. An encoder the build lacks aborts startup.
• Hard constrainttransports accepts only the websocket and http entries; any other value aborts startup, and an empty url makes the http entry a silent no-op while the WebSocket channel still broadcasts.
• FallbackHTTP delivery is asynchronous with bounded exponential-backoff retries; when the in-flight queue is full the oldest pending request is dropped rather than blocking the stream.
• State lifetimeurl can be changed at runtime; the remaining keys are captured once at startup.
