Video to Audio Extractor — MP3 or WAV from Any Clip

A one-hour lecture as MP3 versus WAV

The Video to Audio Extractor pulls the sound track out of any video file and saves it as MP3 or WAV, entirely inside your browser. A real scenario: you recorded a 60-minute lecture. Extracted at MP3 192k — 24 kilobytes per second — the audio lands at about 86 MB. The same hour as 16-bit WAV costs roughly 635 MB, because PCM stores all 44,100 stereo samples every second with zero compression. Either way the video stream is simply discarded, so extraction finishes faster than the lecture ever played, and the file never touches a server. Stereo stays stereo throughout, too — nothing gets collapsed to mono along the way.

Format choice is the whole decision. MP3 192k is right for listening: phone, car, uploads to a transcription service. WAV is for work — audio editing, software that demands lossless, archiving something you can't re-record. One caveat on long recordings: a two-hour meeting as WAV sits north of 1.2 GB, and browser memory on an older laptop may grumble about it. Past the hour mark, MP3 is the sane pick. Transcription services in particular prefer MP3 at 192k: big enough to stay crisp, small enough to upload without pain.
