What Kind of Noise Does It Remove?
The AI model is trained on speech with common background noises: • Fan and AC noise — the constant hum from air conditioners, computer fans, or heaters • Room noise — the ambient sound of an untreated room • Hiss — electrical noise from microphone preamps or gain set too high • Traffic and outdoor noise — cars, wind, street sounds behind your voice • Keyboard clicking — typing during a call or podcast recording The model separates human speech from everything else, preserving voice clarity while removing the background.
Optimized for Speech
This tool is designed for voice recordings — podcasts, interviews, Zoom calls, voice memos, dictation, and lectures. The AI model understands the spectral characteristics of human speech and preserves them while removing non-speech sounds. For music recordings, use a different approach — the noise remover treats instruments as noise and will degrade music quality.
Adjusting Strength
The strength slider controls how aggressively noise is removed: • Light (10-30%) — subtle cleanup, preserves the most natural sound • Medium (40-60%) — good balance for most recordings • Strong (70-90%) — aggressive removal for very noisy environments • Full (100%) — maximum noise removal, may affect voice quality slightly Start at Medium. If you hear remaining noise, increase. If the voice sounds processed or robotic, decrease. The right setting depends on how much noise your recording has.

Yes. Phone call recordings with background noise are a common use case. The AI is optimized for speech, so it handles phone-quality audio well. Set strength to Medium or Strong depending on the noise level.
The AI is trained exclusively on speech. It interprets musical instruments as noise and tries to remove them. For speech recordings with background music, the music will be partially removed along with the noise.
