THE SOUNDTRACK, SAVED
Images, video & audioAudio Extractor — pull sound out of any video
The lecture recording, the interview, the concert clip — extract the soundtrack as a clean WAV, decoded and re-encoded on your device as PCM 16-bit.
Runs locally in your browser. Your files never upload.
Half of what happens in a video is the audio: the lecture you want to relisten to on the commute, the interview for your research, the soundtrack worth keeping when the video is not. The Audio extractor separates them cleanly — drop in the video, get out the sound as a WAV file, and the video becomes optional.
The output is uncompressed PCM 16-bit WAV, the format everything can read and nothing has to decode cleverly. It is the archivist's choice: no quality lost to a lossy round-trip, and full freedom to compress or convert afterwards with the Convert tool if a smaller format is wanted.
The decoding and re-encoding happen on your device. A lecture recording with voices you care about, an interview with someone who trusted you — these are exactly the files that should not be uploaded to a converter website, so they never are.
Free, no account, no upload. Extract the sound, keep the sound, done.
