## What this tool does

Hum reduction plus brush-selection spectral attenuation: drag rectangles over frequencies and time to remove or reduce isolated sounds, then process to preview.

Drag across time (horizontal) and frequency (vertical). Multiple selections supported. Frequency is logarithmic from approximately 18 kHz at top to 35 Hz at bottom.

Selected areas are attenuated by the repair intensity control. A simple STFT mask may create ringing or musical noise on complex material.

Audio processing is local to your browser. Use uncompressed source audio for best results. A 24-bit WAV export preserves PCM precision; it does not restore quality lost in MP3 sources.

Hum reduction plus brush-selection spectral attenuation: drag rectangles over frequencies and time to remove or reduce isolated sounds, then process to preview. Free for creators from DJ Boothby Eddie B.

Inspect the spectrogram, select the affected time and frequency region, reduce unwanted energy and audition the result.

Spectral attenuation is selective editing, not perfect sound reconstruction. Heavy processing can alter nearby wanted sounds.

## Important information

Capabilities and formats depend on the selected application, browser and device. Check the interactive app and the Help Center before relying on an exported file.
