flexaudio-core

OS-agnostic engine, types, and normalization pipeline for the flexaudio workspace.

This crate is the shared foundation that all flexaudio backends and the facade depend on. It provides:

• Shared types — AudioChunk, StreamConfig, SourceKind, OutputFormat, DeviceInfo, DeviceEvent, Error, etc.
• CaptureBackend trait — the contract every OS backend implements.
• Two-stage ring-buffer pipeline — raw RT ring (rtrb) → Normalizer (mix + rubato SRC) → 20 ms chunk ring (ringbuf).
• Normalizer — converts arbitrary native formats to the fixed internal canonical form (48 kHz / stereo / interleaved f32 / 20 ms chunks), then optionally re-converts to the caller-chosen OutputFormat in a second stage.
• Clock utilities — ClockNormalizer, monotonic_now_ns.

Most users should use the flexaudio facade crate instead of this one directly. Depend on flexaudio-core only if you are implementing a custom capture backend that plugs into the CaptureBackend trait.
