How to remove background noise from a podcast

Turn on the AI Noise Remover and start at Subtle — not Strong. It strips hiss, hum and room noise while leaving music and effects alone, and because your original is never overwritten, you can compare strengths and keep the one that still sounds like you.

Step by step

01Open Polish in the Voice EditorThe AI Noise Remover lives beside the transcript, with four settings: Off, Subtle, Medium, Strong.
02Start at SubtleGo up only if you still hear the noise. Heavy reduction is what makes a voice sound processed and hollow.
03Compare against the originalToggle it off to hear the raw take. A quiet, clean room may not need cleanup at all — Off is a setting on purpose.

If the voice comes back robotic

That is the signature of noise reduction working too hard, and the fix is one move: lower the strength. The trade-off is real physics — the more aggressively noise is removed, the more voice goes with it — which is exactly why the dial exists. Noise removal costs no credits, on any plan.

FAQ

01How does noise removal work?

Turn on the AI Noise Remover. It strips hiss, hum and room noise from the voice while leaving music and sound effects alone, and it has four settings — Off, Subtle, Medium, Strong — so you can control how hard it works.

02The cleanup made my voice robotic — how do I fix it?

Lower the strength. Robotic, hollow or underwater artifacts are the signature of noise reduction working too hard — drop from Strong to Medium or Subtle and the voice comes back. Nothing is lost by doing this: your original recording is untouched and the setting is reversible.

03Can it remove echo too?

Not as a dedicated control — Cast has no de-reverb. Noise removal targets steady noise (hiss, hum, room tone), and it will not pull the echo out of a recording made in a bare, reflective room.
