Frequently Asked Questions
Does the Audio Extractor upload my video to a server?
No. The entire decoding and audio encoding process runs locally inside your browser using the HTML5 Web Audio API. Your video file never leaves your computer or phone.
Does extracting audio as WAV maintain original quality?
Yes. The tool extracts uncompressed 16-bit linear PCM audio samples directly from the decoded stream, preventing generational compression loss and ensuring maximum sound clarity.
What happens if a video has no audio track?
If the selected video file does not contain an audio stream (or uses an unsupported audio codec like AC3/DTS), the tool detects this immediately and displays a clear message informing you that no audio track was found.
Which video formats are supported for audio extraction?
You can extract audio from all video containers natively playable by your web browser, including MP4 (AAC/MP3 audio), WebM (Opus/Vorbis audio), and MOV.
