This tool vs. Voice Cleaner
This is a general-purpose denoiser that works on any audio — music, field recordings, or speech — with a strength slider you control directly.
If your source is specifically speech (a podcast, phone recording, or interview), the Voice Cleaner runs a fixed chain tuned just for that — rumble cut, speech-optimized denoise, and loudness normalization in one pass — and will usually outperform manually tuning this tool for voice content.

Frequently asked questions
What kind of noise does this remove?

Should I use this or the Voice Cleaner for a podcast?
For speech-only recordings, the Voice Cleaner's fixed speech-tuned preset generally works better. Use this tool when you want direct control over reduction strength, or for music and non-speech audio.
Is this really free?
Yes — completely free, no sign-up, no watermark on the output.
What formats are supported?
MP3, WAV, FLAC, M4A, AAC, OGG, and AIFF, up to 50MB and 20 minutes long.
