How to record mobile phone recordings in mp3 format?

Take the Android phone as an example, we can choose MP3 format for recording, and the specific steps are as follows:

1. First, we turn on the phone, find it from the phone and enter the "recorder"

2. After entering the recording interface, click the setting button in the upper right corner to enter the setting interface

3. Then we find the recording format option in the settings and click Open

. In this way, the recorded file becomes the expanded data in MP3 format

1. Advantages of MP3 format:

1. Because of its small file size and good sound quality; The status of this format as a mainstream audio format is still difficult to shake.

2. The sampling frequency of compressed music in MP3 format is varied, which can save space with a sampling frequency of 64Kbps or lower, and can also achieve extremely high sound quality with a standard of 32Kbps.

3. Compared with other audio format files, MP3 format audio files occupy less storage capacity.

2. Disadvantages of MP3 format:

1. The compression of audio files in MP3 format is a lossy compression.

2. MP3 format audio coding has a high compression ratio of 1: 1 ~ 12: 1, while basically keeping the low audio part undistorted, but sacrificing the quality of the high audio part from 12KHz to 16KHz in the sound file.

3. MP3 files may not be played on some players. Because the default CBR (fixed sampling frequency) technology can sample a song at a fixed frequency, while VBR (variable sampling frequency) can increase the sampling frequency when the music is "busy" to obtain higher sound quality. The MP3 file generated in this way may not be played on some players.
