For podcast & audio editors
Did your noise reduction actually make it better?
Load your before and after — the raw take and your cleaned-up edit — and listen blind and level-matched, without knowing which is which. Only after you choose do you see whether your cleanup helped or just added artifacts.

How it works
Load before & after
Drop in your raw take and your cleaned-up version of the same clip. No DAW, no account, no upload — it all runs in the browser.
Listen blind, level-matched
They're labeled A and B at random and loudness-matched automatically, so you're judging the cleanup — not which one happens to be louder.
Reveal the winner
Commit to the one that sounds better, then see which was which. Sometimes the raw take wins — and that's the most useful answer of all.
Questions podcast editors ask
How do I tell if my noise reduction made my podcast sound worse?
Compare the before and after blind and level-matched. If you can't reliably pick the processed version as the better one, your noise reduction is adding artifacts you've stopped noticing rather than improving the audio.
How do I A/B two podcast edits without fooling myself?
Hide which is which and match their loudness. Knowing which take is the new one — or letting one play slightly louder — biases your judgment before you've heard a thing. Blind Listen removes both.
Does louder always sound better when comparing audio?
Effectively, yes — even a decibel or two of extra loudness reads as 'better' to human ears. That's why every comparison here is level-matched first.
Do my audio files get uploaded anywhere?
No. Everything runs locally in your browser. Your files never leave your machine.
