The best audio extractor for extracting audio from video file?

One remind. Please don't use an online audio extractor though it is free.

Privacy Risks: Online audio extractors require you to upload your video files to their servers, exposing potentially sensitive or private content to third parties. Even if the service claims to delete files after processing, there’s no guarantee your data won’t be stored, misused, or hacked. 

Quality and Limitations: Many online audio extracting tools compress audio heavily or restrict output formats, resulting in lower-quality files. Some also impose file size limits, watermarks, or require subscriptions for basic features. Desktop apps preserve original quality and offer customizable settings without artificial restrictions.

Unreliability and Ads: Free online extractors often bombard users with ads, pop-ups, or malware. Servers can be slow, and the site might vanish unexpectedly, leaving you without your files. Local tools work instantly, offline, and without hidden costs, making them faster and more dependable for long-term use.
