About Audio Noise Remover
OptiPix Audio Noise Remover cleans up audio recordings by removing background noise directly in your browser. Choose from preset noise reduction levels (Light, Medium, Strong) or use the high-pass filter to remove low-frequency rumble common in voice recordings. The noise gate silences audio below a threshold to eliminate constant background hum. Preview the cleaned audio with A/B comparison before downloading. Uses FFmpeg.wasm filters for professional noise reduction. Your audio files never leave your device.
How It Works
The tool uses FFmpeg.wasm audio filters: highpass for removing low-frequency rumble, anlmdn (non-local means denoising) for noise reduction, and volume-based gating for silencing quiet background noise.
