Can I extract audio from 4K and HD videos?

Yes. FFmpeg demuxes the container and extracts the audio stream directly without having to decode heavy video frames, making it fast even for high-resolution video files.

What audio bitrate is used?

The output MP3 is encoded at 192 kbps, providing clear, CD-like audio quality suitable for music, speech, and podcast listening.
