Plenty of FLVs were only ever about their audio: music ripped from the video sites of the 2000s, recorded radio streams, captured interviews. Extracting just that track decodes the era's audio codecs in software and writes a 256 kbps AAC file, skipping video work entirely and finishing quickly. The M4A plays on everything current. Files whose picture matters too have the full MP4 conversion one page over; this route is for the sound.
Questions
What audio hides in FLV files?
Usually MP3 or early AAC, both decoded cleanly here. Obscure Flash-specific audio fails with its name given.
Is this faster than converting to MP4 first?
Considerably: no video frames are decoded or encoded, which is where all the time goes.
Uploaded anywhere in the process?
No, extraction runs in the browser.
