Among audio formats, AAC offers excellent compression efficiency and sound quality. Whether it's the default audio format for Apple devices or support from major platforms like YouTube and iTunes, AAC is widely compatible. If we want to extract audio from the large amount of video footage we accumulate—such as live band performances, course lectures, or important meeting recordings—and save it in the higher-quality AAC format to a music library or mobile device, converting hundreds or even thousands of video files one by one is an enormous workload.
This article will talk about how to batch convert multiple video formats such as MP4, AVI, and MOV to AAC audio files, preserving the original recording details in full while keeping the file size small.
Why batch convert MP4 and MOV videos to AAC audio?
Save storage space
Video files like MP4 and MOV usually have a large size, containing both video and audio components. If only the audio is needed, they can be batch converted to the AAC audio format, making the files much smaller and taking up less space.
Convenient playback and management
Audio files are easier to manage than videos and can be directly placed into a music player or audio software for playback. When driving or exercising, listening to audio only is more convenient without needing to keep the screen on. After batch converting to AAC, you can categorize, name, and sort them just like organizing songs.
Improve processing efficiency
When you have a lot of video material and need to extract audio, manually handling them one by one can be very tedious. By batch converting to AAC, you can process multiple files in sequence, saving a lot of time. For those who need to organize audio files, this method is simpler and more efficient.
