Frequently asked questions
What threshold and duration settings should I use for podcasts?+
A good starting point is −40 dB threshold with 0.5 second minimum silence duration. This removes dead air pauses while preserving natural short pauses mid-sentence. For highly noisy recordings (background hum), raise the threshold to −35 dB. For more aggressive tightening, reduce minimum duration to 0.3 seconds.
Will it accidentally cut breaths or short pauses?+
With the default 0.5 second minimum duration, very short natural pauses and breath gaps (typically under 0.3 seconds) are preserved. If you find natural speech rhythm is being interrupted, increase the minimum silence duration to 0.7 or 1.0 seconds.
Can I use silence stripping on music or non-voice audio?+
Yes, but results vary. For music with soft passages (classical, acoustic), the silence stripper may cut intentional quiet sections. It is most effective on speech recordings where the intended content is consistently above the threshold. For music editing, use the audio trimmer for manual control.
