Noise Reduction Guide
Learn how NoiseReducer.net removes unwanted background sounds while preserving voice clarity.
Types of Noise We Handle
Static Noise (Best Results)
Continuous, predictable sounds that our algorithms handle exceptionally well:
- Air conditioning and HVAC systems
- Computer fans and hard drives
- Electrical hum (50/60Hz)
- Tape hiss and microphone self-noise
- Traffic rumble
Dynamic Noise (Limited Results)
Unpredictable sounds that are more challenging:
- Other people talking
- Dog barking, phone ringing
- Keyboard typing
- Background music
Important: NoiseReducer.net is optimized for static noise. We cannot fully remove distinct sounds like speech or music without affecting your main audio.
How It Works
- Analysis: We identify the noise characteristics in your audio
- Processing: Advanced filtering separates noise from voice
- Enhancement: The cleaned audio is optimized for clarity

FAQ
Will it affect my voice quality?
With moderate noise levels, your voice should remain natural. Very heavy noise may result in slight artifacts.
Can I remove other people's voices?
No. Our tool targets static noise. Removing distinct voices requires different technology that can significantly affect audio quality.
