Part 1: When Audio Should be Extracted from MP4?

When do you need to extract audios from a MP4 video? We have summarized the following two points:

1. When you listen to beautiful music in a video, you can save the audios to enjoy at any time.

2. You want to save the lines of the video only.

Part 2: How to Select Output Format?

The common audio formats are: MP3, WAV, APE, FLAC, AAC, etc. Which one is better? We recommend MP3 because:

1. MP3 provides rendering capability at high bitrate, and it performs excellent sound effects. The file size is not large.

2. MP3 has a variety of sampling rates. It can save space with the sampling rate of 64kbps, or even lower. Besides, it reaches to the higher quality at 320kbps.
