How to Remove Background Noise
Clean up audio recordings by removing unwanted background noise and hiss.
Step-by-Step Guide
Upload Audio File
Select your audio file (MP3, WAV, M4A, etc.) that contains background noise.
💡 Tip: Works best with clear speech recordings with moderate background noise
Choose Noise Type
Select the type of noise: Auto-detect, Hiss, Hum, Wind, or Background noise.
💡 Tip: Auto-detect works well for most scenarios
Adjust Cleaning Intensity
Set cleaning intensity from 10% (light) to 100% (aggressive).
💡 Tip: Start with 30-50% intensity and adjust based on results
Select Algorithm
Choose from Spectral Subtraction, High-Pass Filter, Adaptive, or Combined methods.
💡 Tip: Combined algorithm works best for most noise types
