//! # speech-prep
//!
//! Speech-focused audio preprocessing for Rust.
//!
//! - Voice activity detection (dual-metric: energy + spectral flux)
//! - Multi-format decoding (WAV/MP3/FLAC/OGG/M4A/Opus → 16kHz mono PCM)
//! - Preprocessing (DC removal, high-pass filter, noise reduction, normalization)
//! - Speech-aligned chunking with overlap handling
//! - Quality assessment metrics
//!
//! ## Usage
//!
//! ```rust
//! use speech_prep::VadConfig;
//!
//! let config = VadConfig::default();
//! assert!(config.base_threshold > 0.0);
//! ```
