//! Reusable audio-engine core.
//!
//! This crate owns app-agnostic decoder, DSP, and streaming pipeline building
//! blocks. The application/server crate layers playback control, persistence,
//! HTTP/WebSocket routes, and runtime directory handling on top.
//!
//! # Example
//!
//! Apply a 10-band graphic equalizer to a block of interleaved stereo audio:
//!
//! ```
//! use audio_engine_core::Equalizer;
//!
//! let sample_rate = 48_000.0;
//! let mut eq = Equalizer::new(2, sample_rate);
//!
//! // Boost the lowest band by +6 dB, leave the rest flat.
//! eq.set_band_gain(0, 6.0, sample_rate);
//! eq.set_enabled(true);
//!
//! // Interleaved L/R samples; `process` filters in place.
//! let mut buffer = vec![0.1_f64; 2 * 512];
//! eq.process(&mut buffer);
//! ```
//!
//! See the `examples/` directory for runnable resampling and EQ programs.
