Phone videos, camera clips, Zoom recordings and exported edits are usually MP4 or MOV files with AAC audio inside. This page keeps only that soundtrack, which is handy when you want to clean up an interview, send audio to a transcription tool or reuse a voiceover.
WAV gives editing software uncompressed audio to work on, so noise removal and leveling do not stack new compression on top of the AAC. Expect around 11 MB per minute for 48 kHz stereo, the rate most phones and cameras record at.
A screen recording made without the microphone switched on has no audio track, so there is nothing to extract. If a video has several tracks, the converter keeps the main one. Clips saved from streaming apps are often protected and will not open.
Yes. iPhone MOV files use the same audio format as MP4, so you can drop them in and get a WAV of the soundtrack.
Only the audio is kept. The video track is discarded, which is why the download is audio-only.
No. It converts inside your browser, on your own device. Nothing reaches FacelessGenie or any other server.
Files up to 1 GB work. Long recordings simply take longer on slower devices.
Recent Chrome, Edge and Safari handle every format here. Firefox opens most audio. For WAV problems, Chrome or Edge is the safest retry.
