This tool helps you comprehensively test audio device performance, covering the 10Hz - 21kHz frequency range. Supports precise sine wave generation, sweep analysis, and noise tests, suitable for speakers, headphones, and professional acoustic systems.
Use this tool to accurately detect frequency response characteristics of home theater systems, car audio, and professional monitor speakers, assisting with acoustic calibration and equalizer adjustment.
Quickly determine if headphones have channel imbalance, distortion, or uneven frequency response. Particularly suitable for testing in-ear and over-ear headphones.
Test room acoustic characteristics using white noise and pink noise, identify standing waves, resonance points, and provide data support for room acoustic treatment.
📖 This tool is designed for users seeking audio quality performance, not only testing hardware integrity but also quantitatively evaluating speaker frequency response performance.
Provides waveform generation from infrasonic to ultrasonic frequencies, testing bass driver extension and treble unit performance.
Through 10-second continuous sweep, you can hear smooth tone progression; any noticeable volume fluctuations or distortion indicate uneven frequency response or hardware issues.
Includes acoustically standardized white noise and pink noise, the former for full-range uniformity testing, the latter for sound field calibration and speaker burn-in.
High-quality speakers should produce smooth, continuous sound with stable volume during sweep; if buzzing or distortion occurs at certain frequencies, it usually indicates internal component resonance.
As age increases, human high-frequency perception gradually declines. Additionally, bandwidth limitations of ordinary Bluetooth headphones may filter signals above 18kHz.
