About This Tool
A frequency sweep plays a continuous tone that gradually changes from low to high frequencies. This helps you identify:
- Speaker response: Frequencies where your speakers are weak or strong
- Room acoustics: Resonances or dead spots in your listening environment
- Hearing range: The highest and lowest frequencies you can hear
- Equipment issues: Rattles, distortion, or damaged drivers
Tips for Testing
- Keep volume moderate to avoid speaker damage, especially at low frequencies
- Logarithmic sweep sounds more natural as it spends equal time per octave
- Test in a quiet environment for best results
- Compare left and right speakers using the Speaker Balance Test
Privacy & Limitations
