When MP3 is convenient
MP3 plays on a wide range of devices and editing tools. Conversion is useful if your player needs that format. It cannot increase the detail of a low-quality source, and re-encoding may add loss compared with keeping an original compatible stream.
When an original track is preferable
If the result offers M4A or another source audio file and your device supports it, that option can avoid an extra conversion. The exact track and bitrate depend on the source. The page never promises a fixed 320 kbps output.
Compare the actual choices
Analyze the video, then look at the available extension, bitrate when known and estimated size when available. Use the dedicated audio or MP3 tool for the format you need. A silent or inaccessible video cannot produce a useful audio file.
