A WMV's audio unlocks in a fraction of the time its video takes: only the sound is decoded, so old webinars, narrated decks and recordings shed their listenable content quickly even on the software path. Output is 256 kbps AAC in an M4A, ready for phones, transcription or archives. When the video itself matters too, the full conversion sits on its own page; for the spoken record alone, this is the shortcut.
Questions
How much faster is audio-only extraction?
Typically several times faster than converting the video, since frames are never touched; audio decoding is light even in software.
Will old Windows Media audio decode?
The common variants do. An unsupported one fails with the codec named plainly.
Where does this run?
In your browser; the recording stays private.
