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
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);Re-exports§
