Auto Silence Remover for Video

À propos de l'application

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.
