Main Features

1. Create Audio Descriptions (main feature)
Load any video (MP4, MKV, AVI, WEBM), view the synchronized waveform and place synthetic voice narrations at the exact moments. Each clip can have its own voice, speed and volume. Export as MP4 (video) or MP3 (audio only). Save and resume projects anytime.

Generate automatic subtitles in multiple languages from any video using artificial intelligence. Includes a built-in subtitle editor to correct text and adjust timing. Generate simple automatic dubbing synchronized with the subtitles. Import and export SRT.

3. Book to Audio
Convert entire books (PDF, TXT, EPUB, DOCX) to audio with synthetic voice. Automatically detects chapters and generates MP3 files organized by chapter. Improved conversion engine for greater fidelity and speed.

4. Media Editor
Full audio and video editor with waveform: trim, delete sections, adjust volume (up to 200%), change speed, apply dynamic compression and merge multiple files. Visual selection with drag and markers. Now also allows cutting videos, extracting audio from video, and adjusting brightness and contrast.
