  • Open CMD window.
  • Navigate to the folder where FFMPEG is installed.
  • Use the following syntax:¬†ffmpeg -i <source.flac> -ab 320k -map_metadata 0 -id3v2_version 3 <output.mp3>
    (Here,the syntaxes -ab defines the bitrate of output file, -map_metadata lets you set metadata attributes, and you can also set id3v2 version.)
  • So, if the input mp3 file is named LOF.flac, stored in the installation folder of FFMPEG, and I want to save it as an mp3 file with the name output.mp3, I will use the following command:¬†ffmpeg -i LOF.flac -ab 320k -map_metadata 0 -id3v2_version 3 output.mp3
  • Check for output in the folder where FFMPEG is installed.

SoX (Sound eXchange)

SoX or Sound eXchange is a cross platform, command line audio utility that you can use to encode FLAC to MP3. SoX on its own cannot encode MP3 files, therefore you will need to add LAME encoder library file to SoX for the same. The process is easy to carry out.

After downloading and installing SoX, go to this page, and download the LAME library file (download the zip file, and not the exe file). Unzip the downloaded file, where you will find a .dll file named lame_enc.dll. Rename lame.enc.dll to libmp3lame.dll, then copy the dll file.

Go to the folder where SoX is installed. In the installation folder, paste the libmp3lame.dll file.

How to Convert FLAC to MP3 in SoX:

  • Open Command Prompt, and navigate to the folder where SoX is installed.
  • Use the following syntax: input.flac -C bitrate output.mp3
  • If the input file is named lof.flac, the output bitrate to be set is 320, and the output mp3 file name is output.mp3, you¬†will use the following command: lof.flac -C 320 output.mp3
  • The FLAC file will be converted and saved in the User AppData folder of your PC. For my PC, the output location was:¬†C:\Users\LISTOFFREEWARE\AppData\Local\VirtualStore\Program Files (x86)\sox-14-4-2

The above screenshot displays the result without and with the LAME library installed.
