FFT Denoiser
FFT Denoiser targets noise in the frequency domain — effective on stubborn hiss and hum that a general denoiser might miss.
Parameters
| Parameter | Type | Range | Default | What it does |
|---|---|---|---|---|
| Noise Floor | number | -60 to 0 dB | -30 dB | The level below which audio is treated as noise. |
| Band Noise | number | 0 to 30 dB | 5 dB | Declared as a per-band noise control, but currently has no audible effect — it only applies under a noise mode this app doesn't enable. |
Note: the Noise Floor range shown in the app extends slightly past what the underlying processor treats as valid — keep it around -60 to -20 dB for predictable results.
