speech-prep 0.1.4

//! # speech-prep
//!
//! Speech-focused audio preprocessing for Rust.
//!
//! - Voice activity detection (dual-metric: energy + spectral flux)
//! - Audio format detection plus WAV decoding to 16kHz mono PCM
//! - Preprocessing (DC removal, high-pass filter, noise reduction, normalization)
//! - Speech-aligned chunking with overlap handling
//! - Quality assessment metrics
//!
//! ## Usage
//!
//! ```rust
//! use std::sync::Arc;
//! use speech_prep::{NoopVadMetricsCollector, VadConfig, VadDetector, VadMetricsCollector};
//!
//! # fn main() -> Result<(), speech_prep::Error> {
//! let config = VadConfig::default();
//! let metrics: Arc<dyn VadMetricsCollector> = Arc::new(NoopVadMetricsCollector);
//! let detector = VadDetector::new(config, metrics)?;
//!
//! let audio_samples = vec![0.0; 16_000];
//! let _segments = detector.detect(&audio_samples)?;
//! # Ok(())
//! # }
//! ```
