use ffmpeg

Open Command Prompt (Windows) or Terminal (Mac and Linux) after the installation is complete.

In a command prompt or terminal, navigate to the directory where the M4a or Wav files are stored. You can use the "cd" command to navigate, for example:

   cd D:\sound\ring

Run the following command to convert the file to mp3 format:

   ffmpeg -i 输入文件.m4a 输出文件.mp3
   ffmpeg -i 输入文件.wav 输出文件.mp3

Among them, "input file.m4a" is the name of the M4A file you want to convert, and "output file.mp3" is the name of the MP3 file you want to generate. Please ensure that the input and output filenames are correct and append the appropriate file extension to the filename.

ffmpeg will start the conversion process and display the conversion progress on the command prompt or terminal. Once the conversion is complete, you will find the resulting MP3 file in the same directory, the conversion speed may depend on your computer performance and the size of the M4A file.

Conversion example:

• Convert m4a and wav files to mp3 format

ffmpeg -i Cry_On_My_Shoulder.m4a Cry_On_My_Shoulder.mp3 
ffmpeg -i marimba-ringtone.wav marimba-ringtone.mp3

After the conversion is complete, we get two mp3 files, and the playback test is all normal
