ShortsPacer — Viral Voice Tightener & Studio De-Breath

Turn loose AI voiceovers, dragged narrations, and raw podcast recordings into punchy, broadcast-grade audio in under 0.4 seconds. Built specifically for TikTok, YouTube Shorts, Reels, and fast-paced storytelling.

Stop Losing Viewers to Dead Air & Awkward Breaths

In modern short-form video, the first 3 seconds decide your reach.
Yet most AI-generated voices (ElevenLabs, MiniMax, OpenAI TTS) and raw vocal takes are full of robotic pauses, dragging silences, and loud breathing artifacts that kill retention.

ShortsPacer is a zero-latency audio pacing copilot that surgically trims redundant pauses while keeping 100% natural speech cadence.

Two Core Production Modes

1. Viral Pacing Mode (For TikTok / Shorts / Reels)

• Goal: Maximize audience retention and algorithmic hook velocity.
• What it does: Compresses speech gaps by 15% to 25%, turning dragging paragraphs into crisp, engaging, high-tempo creator delivery.

2. Studio De-Breath Mode (For Podcasts & Audiobooks)

• Goal: Professional acoustic cleanup without the mechanical "vacuum" feeling.
• What it does: Detects and eliminates heavy gasp breaths and low-frequency mouth noises below -38 dB, maintaining vocal warmth and room tone.

How It Works

• Step 1 — Provide Audio: Drag and drop any single audio file, an entire folder, or provide a URL/file path.
• Step 2 — Dual-Threshold RMS Scan: ShortsPacer analyzes energy levels, isolating speech boundaries from breaths and room silence.
• Step 3 — Anti-Click Cosine Crossfading: Unlike primitive cutters that produce clicks and pops, ShortsPacer applies a micro 10ms smooth cosine crossfade across every slice with a 50ms voice-head safety buffer (never clips p/t/k consonants).
• Step 4 — Instant Broadcast Export: Receive high-fidelity 320 kbps MP3 or lossless WAV, accompanied by a verified retention analytics report.

Usage

Run the bundled lightweight processor via CLI:

python3 scripts/shortspacer_engine.py --input <path_or_url> [--output <out_dir>]

Parameters

• --input: Path to a single audio file, directory of audio files, or a public audio URL.
• --output (optional): Destination directory. Defaults to a cleaned_audio folder next to the input.
• --threshold (optional): Silence threshold in dB (default: -38dB).
• --min-silence (optional): Minimum silence length in seconds (default: 0.14).
• --keep-margin (optional): Buffer around speech in seconds (default: 0.06).
