Auto Silence Remover for Video

Tighten every video you record. Silence Cutter automatically detects pauses,
"um", "uh", and dead air in your talking-head videos and trims them out in one
tap — entirely on your phone, with zero internet permission.

Stop wasting hours scrubbing through recordings. Drop in a vlog, podcast,
course lesson, interview, or screen recording — Silence Cutter analyzes the
audio, finds every silence longer than your chosen threshold, and rebuilds
the video without them. Hardware-accelerated export means a 10-minute clip
becomes a 6-minute clip in seconds, not minutes.

WHAT'S INSIDE
• Auto silence detection — RMS energy windowing with adaptive threshold that
tracks the noise floor of each recording. No fiddly per-clip tuning.
• On-device filler-word removal — uses Whisper transcription locally to
identify "um", "uh", "like", "you know" and cut them with the silences.
• Hardware-accelerated export — H.264 + AAC via Android's MediaCodec, no
background CPU melt.
• Smart audio crossfade — 0–200 ms fade at every cut so your edits never
click or pop.
• Three silence handling modes — remove entirely, speed up like a jumpcut,
or keep a short gap.
• Quality presets — original, 1080p, 720p, 480p.
• Batch processing — drop multiple videos, process them all with the same
detection settings, walk away.
• SRT caption sidecar — when you've transcribed, get a perfectly synced
subtitle file alongside your export.
• Project state saved per video — toggle silences, change settings, return
later, pick up where you left off.

WHAT MAKES IT DIFFERENT
Most "silence remover" apps are wrappers around a cloud service. They make
you upload your footage, pay a subscription, and wait. We don't.

• No INTERNET permission. None. Open the app's Data Safety section on the
Play Store — you'll see no data collection, no transmission, nothing.
• No subscription, no in-app purchases, no ads. Free.
• Nothing leaves your device. Your videos, your transcripts, your edits —
they live in your phone's storage and nowhere else.

WHO IT'S FOR
• YouTubers who record long takes and need to tighten them up
• Podcasters editing audio + face-cam footage
• Course creators producing lecture videos
• Founders, salespeople, and content marketers shooting Loom-style updates
• Anyone making talking-to-camera content on a phone

WHAT IT'S NOT
Silence Cutter is a focused trim-the-pauses tool — it isn't a multi-track
editor like CapCut Pro or Premiere. There's no music library, no transitions,
no color grading. We do one job and we do it well.

REQUIREMENTS
• Android 7.0 (API 24) or later
• 50 MB of free storage for the app, plus space for your exported videos
• For filler-word removal (optional): a Whisper GGML model file (75 MB,
install via Settings)

PRIVACY
We don't collect any personal data. We don't request the INTERNET permission.
The only files Silence Cutter touches are the video you import (read-only)
and the export it writes to your gallery folder.
