Most recordings aren't ruined by bad content — they're ruined by bad acoustics. A great take recorded in a room with a fan running, or near a window with traffic noise, sounds amateurish no matter how good the actual talking is. Nohaya's Audio Cleanup tool exists to fix exactly that, without needing audio engineering skills.
What it cleans up
- Background noise and hiss — the constant low-level hum of a room, fan, or AC unit that you stop noticing while recording but that's obvious to every listener afterward.
- Filler words — "um," "uh," and similar verbal tics can optionally be detected and trimmed, tightening up a recording without you having to manually cut every instance.
When to use it
- Before transcription. Feeding cleaner audio into Speech to Text produces a measurably more accurate transcript than feeding it noisy audio directly.
- Before voice cloning. A clean training sample produces a more accurate Voice Clone — noise in the sample can bleed into generated speech.
- Before publishing, period. Even if you're not feeding the audio into another tool, listener tolerance for background noise is lower than most people assume. Clean audio reads as more professional even when nothing else about the production changed.
What it won't fix
Audio cleanup tools are noise reduction, not magic. A recording with severe clipping (audio that was too loud and distorted at the source), extremely overlapping speech, or a fundamentally bad microphone won't come out sounding like a professional studio take — cleanup improves what's there, it doesn't replace a better original recording. The biggest gains come from moderately noisy audio (a quiet room with a noticeable hum or hiss), not severely damaged audio.
A simple before/after habit
If you record regularly in the same space, run one sample clip through Audio Cleanup and compare it side by side with the original. Once you know how much a quick pass improves your typical setup, it's easy to build the habit of cleaning every recording before it goes anywhere near a transcript, a clone, or a publish button.
