A fan behind a podcast microphone

Select a spoken clip that includes a pause. Run cleanup, then compare the fan during that same pause and the consonants in the next sentence. RNNoise may reduce steady noise, but loud noise overlapping speech can remain.

Preserve intelligibility, not just silence

Compare both previews at similar listening levels. If words sound softened or watery, keep the original and improve the recording setup. DenoiseKit converts stereo to 48 kHz mono; it is not a stereo mastering tool.

A cleaner take on everything you record.

GOOD QUESTIONS. CLEAR ANSWERS.

A little less uncertainty.

Everything to know before you hit clean.

What background noise is worth trying to reduce?

Steady fan noise, low hum and light hiss behind speech are useful test cases for RNNoise. Results vary. It does not separate overlapping speakers or restore clipped audio.

How can I record less noise in the first place?

Move closer to the microphone, turn off nearby fans when safe, and record away from traffic. Check a short test with headphones before recording the full session.

What does a free cleanup include?

Process 3 files per local calendar day, up to 5 minutes each, in your browser. Preview both versions and download mono WAV or MP3. No recording upload or signup is required.
