Recommended settings
When it goes wrong
Output too quiet
Cause: The source recording is quiet.
Fix: Run the Volume Normalizer.
One-sided audio
Cause: The source has sound in only one channel.
Fix: Extract as WAV and copy that channel to the other side in an audio editor.
MP3 too big
Cause: MP3 is written at a high-quality setting (-V2); the bitrate cannot be changed.
Fix: For a smaller file, try AAC, which is fixed at 128 kbps.
Questions
Copyrighted music?
Copying for your own private use is allowed in some countries, but sharing or publishing the audio usually needs permission from the rights holder. Check the rights before you use it.
Multiple audio tracks?
Only one track is extracted. FFmpeg picks it automatically, and it is usually the first one. For another track, use `-map` in FFmpeg: `ffmpeg -i input.mp4 -map 0:a:1 -c:a pcm_s16le output.wav` takes the second.
