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. Built by BinaryScript.
