Audex: Video to MP3 Converter

Audex is a fast, easy-to-use video to MP3 converter and audio extraction tool for Android. Pull the audio track out of any video, or convert existing audio files between formats quickly, and right on your device.

WHAT AUDEX DOES

• Extract audio from video files and save it as MP3, M4A, or WAV
• Convert existing audio files between MP3, M4A (AAC), and lossless WAV
• Compress audio to a smaller MP3 with three presets — Small, Balanced, or Quality
• Convert multiple files at once with batch queue processing
• Choose your own output bitrate for control over file size and quality

WHY AUDEX

• Your files are processed entirely on your device — never uploaded anywhere
• No account or sign-up required
• Free to use, supported by ads
• No unnecessary permissions — files are only read when you pick them yourself
• Clean, distraction-free interface built for speed
• Converted files save straight to your device's Music folder, ready to play in any music app or find in any file manager

HOW IT WORKS

1. Pick a video or audio file, or several at once
2. Choose your output format — MP3, M4A, or WAV — and bitrate
3. Tap convert and watch live progress, with time remaining and output size
4. Find your finished files in the built-in library, or open them straight in your favorite player

BUILT-IN LIBRARY

Browse, search, and filter everything you've converted. Play, share, or delete files directly from the app, and revisit your conversion history any time.

WHO IT'S FOR

Whether you need to turn a video into a podcast-ready MP3, pull audio out of a screen recording, shrink a file down for messaging, or just convert between audio formats without desktop software, Audex handles it in a few taps.

Audex is free to use and supported by ads. Your files themselves are never uploaded — all conversion happens locally on your device.
