sound-opus

Opus for a desktop's sound, as wlshare and the zdesk gateway both code it.

• Stream: what a stream is before any sound — the rate and the channels — and with them the block, the frames of samples in every packet, twenty milliseconds.
• Encoder: one Opus packet of every block, from 16-bit or float samples, at a rate its owner may move while it runs.
• Stream::head: the OpusHead a decoder is configured from, which nothing sends: everything in it follows from the stream.
• walk::BitrateWalk: the rate a link will bear, walked under the configured one — down while the link lags, as a ping on the sound's own connection measures it, back up while it keeps up, to a floor fixed here — whether the link is behind, for a sender with silence to shed, and whether to skip sound so what is heard comes back to live. Every stream walks, and its one setting is the ceiling. The same walk for a stream coded by the gateway and for wlshare's, which the gateway tells the rate. docs/walk.md has how it was settled, on examples/walk-sim.rs.

libopus is linked statically, from the prebuilt archive libopus-prebuilt publishes, so nothing of Opus is compiled to build and nothing is installed to run.

Use it by release tag:
