How to convert mp4 to mp3 free in Windows 11?

SoX is a free cross-platform command-line utility designed for processing and converting audio files. Often referred to as the "Swiss Army knife" of audio manipulation, SoX offers a wide array of functionalities that cater to both novice users and audio professionals. Its powerful features make it an invaluable tool for tasks such as format conversion, audio editing, applying effects, and more.

While SoX excels in audio processing, it does not natively handle video files like MP4. To convert an MP4 video to MP3 audio using SoX, you'll need to first extract the audio track from the video. This typically involves using a separate tool to perform the extraction before processing the audio with SoX.
