Remove background noise from recorded speech
A steady fan, microphone hiss or air-conditioning hum can make dialogue harder to follow. Add your recording and start with Medium Noise, then compare the cleaned voice with the original at the same listening level.
Clean up interviews, podcasts and voice notes
Use a section with both speech and pauses to judge the result. Lower the noise reduction if consonants disappear or the voice sounds watery. Voice smoothing changes the final cleanup; small adjustments often keep speech more natural.
Know which sounds may remain
Another person talking over the main speaker, loud music and strong room echo are harder to separate from speech. Preview the whole passage before using the cleaned audio in a podcast, lesson or transcript project.
Audio noise removal questions
What should I try first?
Start with Medium Noise, then compare the result with your original. Use less reduction if the voice loses detail.
What do the two sliders change?
Noise reduction controls how much background sound can be lowered. Voice smoothing adjusts the final cleanup. Small changes help preserve a natural voice.
Can this remove another person talking?
Overlapping voices and strong room echo may remain. This tool works best on steady background noise around a clear speaker.
Can I clean a long interview?
Yes, within the 300 MB file limit. Longer recordings need more processing time. Preview the cleaned speech before saving it.
How do I reduce background noise from audio online?
Choose a recording and try Medium Noise first. Compare it with the original, adjust Noise reduction and Voice smoothing, then download the result when the voice sounds clear enough.
Can I remove hiss and fan noise from a voice recording?
The tool is suited to steady background sounds such as hiss, fans and room hum around speech. Results depend on the recording; distortion, overlapping voices and strong echo may remain.
