Sound Strip - Audio Extractor

Sound Strip is a simple app that does one thing: extract the audio track from a video file. ■ Lossless Extraction Audio is copied without re-encoding (stream copy), so there's no quality loss — unlike many converter apps that silently degrade audio quality. If your video's audio format isn't supported, you'll get a clear error instead of a broken or low-quality file. ■ Fully Offline All processing happens entirely on your device. Your video and extracted audio are never uploaded to any server. No internet connection required. ■ Simple, Minimal Design Pick a video, extract the audio. That's it. No clutter, no unnecessary settings. ■ Extraction History Play back, share, or delete any of your past extractions right from the app. ■ About Ads Sound Strip is free to use. Ads are kept to a minimum — none on first launch, and no more than once per session with at least 5 minutes between ads. ■ Remove Ads A one-time purchase removes ads permanently. No subscription, no recurring charges — just pay once. Great for: ・Pulling audio from long live-stream or concert recordings ・Reviewing lesson or meeting recordings by audio alone ・Saving space by converting bulky video files into lightweight audio Input: standard video files with AAC audio.
