Examples & decisions
Read the companion story| Control / format | Current starting value | How to use it |
|---|---|---|
| Threshold | −45 dB | Less negative removes more quiet material |
| Minimum quiet duration | 300 ms | Qualifies a run; does not set retained pause |
| Padding | 50 ms on each side | Protects the edges of each quiet run |
| Export | 16-bit PCM WAV / 192 kbps MP3 | Further editing / smaller sharing file |
Parameter / option
| Parameter / option | What it changes |
|---|---|
| Silence threshold | Frames quieter than this count as silence. Raise it to also cut quiet breaths. |
| Minimum silence length | Shorter pauses are kept, so phrasing survives the trim. |
| Keep padding around cuts | Silence left before and after each cut to avoid clipped words. |
