Extract Audio from Any MP4 — Interviews, Lectures, Music Videos
MP4 is the most widely used video format on the web. Video interviews, recorded webinars, course lectures, and music videos all arrive as MP4.

Frequently Asked Questions
Does the MP4 file get uploaded to a server?
No. Extraction runs entirely in your browser using the Web Audio API. The MP4 file is read from your local disk into browser memory and never sent to any server.
Will the WAV audio be the same quality as the audio in the MP4?
The WAV output is 16-bit PCM at the sample rate of the decoded audio. The audio inside most MP4 files is AAC (lossy), so the WAV is uncompressed but the quality ceiling is that of the original AAC encoding. You are not losing additional quality by extracting to WAV, but you are not recovering quality that was lost when the AAC was originally encoded.
What audio codec is inside an MP4?
Most MP4 files use AAC audio at 128 or 192 kbps. Some older files use MP3 audio inside the MP4 container. High-end video files from certain cameras may contain PCM audio inside MP4. The extractor handles all of these as long as your browser supports the codec.
Is there a file size limit?
There is no server-imposed limit since everything runs in your browser. Very large files (several GB) may push against available browser memory on lower-powered devices. For typical video clips up to a few hundred MB, extraction works without issue.
How long does extraction take?
Extraction typically completes in a few seconds for most video clips. The browser decodes and re-encodes audio faster than real time on modern hardware.
Can I convert other video formats like MOV or MKV to WAV?
Yes. Use the MOV to WAV page for QuickTime MOV files, the MKV to WAV page for Matroska MKV files, or the general Audio Extractor which accepts any video format your browser can decode.
