Remove Background Noise from Audio Online

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.

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.

Voice and Podcast for speech, the difference being how much of the room they are willing to remove along with the noise. Music when there is anything worth preserving underneath — it treads far more carefully, because a noise reducer that does not know it is looking at music will happily eat the reverb tail off a cymbal. Hum Removal is the narrow one, for mains hum and its harmonics. AI runs DeepFilterNet and is the one to reach for when the noise is not steady: traffic, a café, wind.

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.

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.

Stop pushing, because past a point the reducer is no longer removing noise but removing the recording. What is left at Maximum is usually noise that lives in the same frequencies as the voice, and nothing can pull those apart by level alone — that is exactly what the AI profile is for, since it separates by what the sound is rather than by how loud it is. If that also leaves it, the honest answer is that the take needs re-recording; a voice at the same level as the room cannot be rescued without the room coming with it.
