//! DSP utilities for audio signal processing
//!
//! This crate provides:
//! - **Signal generation**: Test signals (tones, sweeps, noise)
//! - **Signal analysis**: FFT-based frequency analysis, microphone compensation
//! - **Acoustic metrics**: RT60, clarity (C50/C80), THD, spectrogram
//!
//! # Example
//!
//! ```rust
//! use math_audio_dsp::{signals, analysis};
//!
//! // Generate a 1 kHz tone
//! let signal = signals::gen_tone(1000.0, 0.5, 48000, 1.0);
//!
//! // Analyze a WAV file
//! let config = analysis::WavAnalysisConfig::default();
//! // let result = analysis::analyze_wav_buffer(&signal, 48000, &config);
//! ```
