1//! # aurum-core
2//!
3//! Reusable **on-device speech I/O** library (experimental API).
4//!
5//! - **STT** — local whisper.cpp by default; optional OpenRouter
6//! - **TTS** — local ONNX KittenTTS (cargo feature `tts`, default on)
7//! - **Cleanup** — rules or optional LLM post-edit
8//!
9//! Tagline: *Speech both ways. On-device by default.*
10//!
11//! The API may change without notice until a deliberate major version.
12//!
13//! ## STT example (provider path)
14//!
15//! ```rust,no_run
16//! use aurum_core::audio::{AudioInput, WHISPER_SAMPLE_RATE};
17//! use aurum_core::pcm::PcmBuffer;
18//! use aurum_core::providers::{LocalWhisperProvider, TranscriptionOptions};
19//! use std::path::PathBuf;
20//!
21//! # async fn demo() -> aurum_core::error::Result<()> {
22//! let provider = LocalWhisperProvider::new(PathBuf::from("/tmp/aurum-cache"))
23//!     .with_progress(false)
24//!     .with_local_only(false);
25//! provider.preload("tiny-q5_1").await?;
26//!
27//! let mut buf = PcmBuffer::dictation();
28//! buf.push(&[0.0f32; 1600])?;
29//! let result = provider
30//!     .transcribe_pcm(
31//!         buf.samples().as_slice(),
32//!         &TranscriptionOptions {
33//!             model: "tiny-q5_1".into(),
34//!             language: "en".into(),
35//!             timestamps: false,
36//!             cancel: None,
37//!         },
38//!     )
39//!     .await?;
40//! let _ = AudioInput::from_pcm_slice(buf.samples().as_slice(), WHISPER_SAMPLE_RATE)?;
41//! println!("{}", result.text());
42//! aurum_core::providers::local::clear_context_cache();
43//! # Ok(())
44//! # }
45//! ```
46//!
47//! ## Engine path (preferred for library hosts)
48//!
49//! ```rust,no_run
50//! use aurum_core::AurumEngine;
51//!
52//! # fn demo() -> aurum_core::error::Result<()> {
53//! let engine = AurumEngine::load()?;
54//! let _ = engine.doctor();
55//! let _ = engine.support_bundle(None);
56//! // engine.transcribe_pcm(&samples, &opts).await?; // STT on engine pools
57//! engine.shutdown(); // closes + clears idle models in *this* engine only
58//! # Ok(())
59//! # }
60//! ```
