A recorded call is mostly a static screen wrapped around the part that matters, the discussion. Extracting to M4A converts the WebM's Opus or Vorbis audio to 256 kbps AAC, a small fraction of the file that transcribers, phones and note archives all accept. Speech converts cleanly. Trim off the waiting-room minutes with the start point control. The recording is processed entirely in your browser, which is fitting for internal meetings.
Questions
Is the speech quality kept through conversion?
Yes; converting Opus speech to 256 kbps AAC is far above the threshold where voice degrades audibly.
Can I skip the empty first minutes?
Set the start trim to where the meeting actually begins; only that span converts.
Does the recording upload?
No, extraction is local, appropriate for private calls.
