Audio Cleanup
Remove background noise, silence, and filler words from any recording.
Free, No Account
Audio Cleanup takes a raw recording and removes the parts that make it sound unpolished — background noise via spectral denoising, dead silence at the start/end and between phrases, and filler words like "um" and "uh" (detected via real speech-to-text word timing, not a gimmick). Upload a WAV file and choose which cleanup steps to apply.

Frequently Asked Questions
What audio format does it accept?+
WAV files. Convert other formats to WAV before uploading.
How is 'filler word removal' detected?+
Real speech-to-text word-level timing identifies words like 'um' and 'uh' and cuts those exact spans — not a placeholder feature.
Is the noise reduction real or just a number?+
It's measured directly from the actual noise floor of your file before and after processing, not a fabricated score.
