Auto Silence Remover

1-Click Voice & Muted Gap Trimmer for Adobe Premiere Pro & After Effects

---

⚡ Overview

Auto Silence Remover is a fast, automated CEP extension for Adobe Premiere Pro (and compatible with After Effects) that eliminates silent pauses, dead air, and muted intervals in recorded speech, podcast dialogues, tutorials, and video clips in a single click.

It analyzes audio waveforms with custom decibel thresholds, calculates speech boundaries with anti-word-clipping padding, and reconstructs seamless timelines instantly.

✨ Features

• ⚡ Single-Click Silence Trimming: Select any voice or video clip in your timeline, press the button, and all muted gaps are gone.
• 🎚️ Smart Decibel (dB) Threshold: Configure custom silence thresholds (e.g., -35 dB) to cleanly separate room tone/noise from active vocal dialogue.
• ⏱️ Minimum Gap Duration: Specify minimum pause duration (0.40s default) to preserve natural pauses within sentences while removing long dead air.
• 🛡️ Voice Padding (Margin): Built-in pre- and post-speech margins (0.08s default) protect the first and last syllables of words from being clipped.
• 🚀 1-Click Installer: Automated .bat script enables Adobe debug registry modes and copies extension files into the target CEP directory automatically.
