## What is AcoustaLab?

AcoustaLab is a professional audio and acoustic test toolkit for speakers, headphones, rooms, and playback equipment.

KEY FEATURES
- Guided tests: Run step-by-step reference tone, sweep, noise, left/right channel, and low-frequency checks, with saved test history.
- Tone generator: Reach target frequencies quickly with logarithmic control, precision fine tuning, and multiple waveforms.
- Sweep testing: Choose single, fixed-count, or continuous loops with direction and interval controls.
- Noise tools: Generate white, pink, or brown noise with filter controls.
- Real-time spectrum: View live frequency-band response from the device microphone for acoustic checks and calibration.
- Presets: Save, import, export, and share reusable test configurations.
- Calibration reports: Generate and share PDF, CSV, and response-curve PNG files.
- Route overview: Confirm active input, output, and sample rate before testing.

Test results can be shared as polished English or Chinese cards. Signal generation, analysis, test history, and report creation are processed locally on your device. Microphone audio is never uploaded. AcoustaLab contains no advertising and does not track users.
