Shorten Long Audio Pauses
Upload a recording, set the longest pause you want to keep, and tighten long silences locally in your browser.
Tighten long pauses without making speech sound chopped
Upload a podcast clip, interview, lecture, or voice note and this tool shortens only the pauses that are longer than your chosen limit. Short natural pauses are left alone; long gaps are capped to the target pause length with ffmpeg's silenceremove filter.
Worked example
A voice note has several awkward two-second gaps. Upload voice.m4a, leave Silence threshold at -30, set Shorten pauses longer than to 1.5, and Keep this much pause to 0.5. The exported voice-tightened.mp3 keeps half-second breathing room but removes the dragging dead air.
When to adjust the threshold
Use a more negative threshold such as -40 if the room is quiet and breaths should not count as silence. Use a less negative threshold such as -25 if the recording has background noise and long gaps are not being detected. The defaults are tuned for spoken-word recordings.
Limits and edge cases
- Input files up to 10 MiB; any audio format ffmpeg can decode should work.
target_pausemust be less thanmax_pause, otherwise the edit would be a no-op.- Leading silence is preserved intentionally. Use
audio-silence-removeif you want to strip leading/trailing dead air aggressively. - Output is re-encoded to mp3, wav, ogg, flac, or m4a. Embedded album art is dropped.
FAQ
How is this different from removing silence?
Removing silence can make speech sound jumpy because every pause is cut down to almost nothing. This tool only caps pauses above your limit, so normal short pauses remain and long gaps become a consistent natural beat.
What values should I start with for podcasts?
Start with threshold_db=-30, max_pause=1.5, and target_pause=0.5. For a tighter edit, lower max_pause to 1.0 and target_pause to 0.25. For a more relaxed edit, keep target_pause around 0.75.
Why did some pauses stay untouched?
Pauses shorter than Shorten pauses longer than are intentionally left alone. If a long gap remains, the audio may not be quiet enough to cross the threshold; try a less negative threshold such as -25.
Is my audio uploaded anywhere?
No. The page runs ffmpeg WebAssembly in your browser tab, so your audio stays on your device. The CLI/chat version uses the same ffmpeg plan through the local tool runtime.
