Step 1: Import Your Noisy Recording
Upload your voice memo, podcast track, or video audio into the [AI Noise Reduction Tool](file:///audio-enhancement/remove-background-noise/).
Step 2: Choose Noise Profile Method
For best results, highlight 0.5–1.0s of pure background noise on the waveform and select 'Use current selection'. Alternatively, use 'Auto-detect'.
Step 3: Set Reduction Strength
Start with 50% strength. This achieves maximum noise reduction without causing vocal phasing or watery artifacts.
Step 4: Apply and Export
Click 'Apply Noise Reduction'. Our in-browser TensorFlow engine processes each frequency bin and replaces your clip with clean, quiet audio.
