Frequently asked questions
Does it also remove silences in the middle?
No: only the start and the end. Mid-file silences are usually intentional (pauses), and we prefer not to touch them.
Which sensitivity should I pick?
Start with medium (−45 dB). If background-noise silence remains, try aggressive; if it cuts breaths, soft.
What if there is no silence?
The audio comes out unchanged: detection only trims what is genuinely below the threshold.
