Frequently Asked Questions
How does the noise removal work?
The tool uses advanced spectral analysis (FFT-based denoising) to separate noise from useful audio signal. You choose one of five profiles — Voice, Podcast, Music, Hum Removal, or AI — and the algorithm is optimized for that specific type of content, preserving voice clarity and musical detail.
Which noise profile should I choose?
Choose "Voice" for phone calls, meetings, and voice memos. "Podcast" for interviews and talk recordings — it also normalizes loudness. "Music" for songs and instrumentals — gentle processing to preserve dynamics. "Hum Removal" for recordings with electrical buzz. "AI" uses a neural network for the best results on complex, non-stationary noise.
Are my files uploaded to a server?
No. All processing happens locally in your browser using WebAssembly technology. Your audio files never leave your device. This guarantees complete privacy — no one can access your recordings.
What types of noise can be removed?
The tool effectively removes: background hiss, fan and AC noise, room ambience, electrical hum (50/60 Hz), wind noise, keyboard and mouse clicks, and general background chatter. It works best on consistent background noise rather than sudden loud sounds.
Will noise removal affect audio quality?
With Light and Medium strength, the tool removes noise while preserving natural audio quality. Stronger settings may slightly affect tone — use the A/B comparison to find the right balance. The Music profile is specifically designed for minimal impact on audio quality. For further improvement, try the audio enhancer to boost clarity and normalize volume after denoising.
What is the maximum file size?
You can process files up to 1 GB. Since all processing happens in your browser, larger files may take more time depending on your device. Files over 150 MB may cause slowdowns on devices with limited RAM.
