For clean recordings, -50 dB works well. For recordings with background noise, try -35 to -40 dB. Listen to a preview and adjust as needed.
Yes. Set the minimum silence duration to your preferred cutoff (e.g., 1 second). Only silences longer than that value will be removed.
No. The minimum duration setting prevents cutting micro-silences within speech. Setting it to 0.3 seconds or higher protects natural word gaps.
