Common Inquiries

Audio Extraction FAQ

Answers to common questions regarding audio formats, extraction speeds, and client privacy.

Does extracting audio re-encode or compress the sound quality?
No. FrameExtract uses native mp4box.js container demuxing to rip the exact raw bitstream (such as 320kbps AAC, Opus, or PCM audio) directly out of the video container without transcoding, ensuring 100% bit-for-bit lossless fidelity.
Can I extract audio from private meetings, voice memos, or legal recordings?
Yes, with total confidence. Because FrameExtract runs 100% locally in your browser sandbox, not a single byte of your audio or video is ever uploaded to a remote server. You can even disconnect your internet after loading the page.
What output audio formats are supported?
You can extract the original native audio stream (AAC for MP4/MOV, Opus/Vorbis for WEBM) or transcode to standard uncompressed WAV or MP3 files for maximum player compatibility.
Is there a limit on video duration or file size?
There are zero arbitrary limits. You can drop a 2-hour, 10GB video into the tool, and the audio stream will demux in seconds directly in your local browser memory.
