Frequently Asked Questions

What types of background noise can this tool remove?
Light Cleanup handles hiss, fan noise and mild room noise. Balanced Voice Cleanup, Strong Noise Removal and Voice Isolation use advanced local speech enhancement that suppresses steady noises such as fans, air conditioners, traffic and microphone hum. Results depend on the recording.
Can it remove background music?
Some music may be reduced, but loud music is not guaranteed to be completely removed. This tool is a speech enhancer, not a full source-separation system.
Can it remove another person speaking?
No tool can perfectly isolate one voice from overlapping speech. Voice Isolation focuses strongly on the main speaker and suppresses background sound, but two people speaking at the same time may still both be audible.
What is Voice Isolation?
Voice Isolation is the strongest speech-focused mode. It applies the most aggressive local speech enhancement so the spoken voice is prioritised. Complex overlapping voices or loud music may not be completely removable.
Does FreeTools upload my audio to a third-party service?
No. Your audio is processed entirely on FreeTools' own servers using free, self-hosted tools — no external noise-removal service or paid API is involved.
Is background-noise removal free?
Yes! The FreeTools Guru Remove Background Noise tool is completely free with no signup required. Each file can be up to 50 MB and 30 minutes long, and you can upload up to 20 files per job.
Why does Strong mode change the voice slightly?
More aggressive noise removal can smooth the voice slightly or remove a little of the natural room ambience. Balanced Voice Cleanup is the recommended default because it keeps voices most natural.
Which mode should I use?
Start with Balanced Voice Cleanup for most speech recordings. Use Light Cleanup for quick touch-ups of mildly noisy audio, Strong Noise Removal for noisy environments, and Voice Isolation when you want to prioritise the speaker above everything else.
