1//! DSP utilities for audio signal processing
2//!
3//! This crate provides:
4//! - **Signal generation**: Test signals (tones, sweeps, noise)
5//! - **Signal analysis**: FFT-based frequency analysis, microphone compensation
6//! - **Acoustic metrics**: RT60, clarity (C50/C80), THD, spectrogram
7//!
8//! # Example
9//!
10//! ```rust
11//! use math_audio_dsp::{signals, analysis};
12//!
13//! // Generate a 1 kHz tone
14//! let signal = signals::gen_tone(1000.0, 0.5, 48000, 1.0);
15//!
16//! // Analyze a WAV file
17//! let config = analysis::WavAnalysisConfig::default();
18//! // let result = analysis::analyze_wav_buffer(&signal, 48000, &config);
19//! ```
