How to Make MP3 Files Into 5.1 Surround Sound

by Daniel Hatter

MP3 files are one of the most widely supported audio file format today. Unfortunately, MP3 files do not support 5.1 surround sound transmission by default due to built-in stereo audio encoding. Dolby Digital is the most widely supported surround sound format today; all DVD/Blu-ray movies support it and most video games do as well. Dolby Digital has a technology that will take stereo audio sources (e.g., MP3 files) and convert them to full 5.1 surround sound. This technology is called Pro Logic II and is included with most recent surround sound systems.

Step 1

Turn on your MP3 audio source and your surround sound system, and then switch the input on your surround sound system to the correct input mode (whichever input your CD-playing device is plugged into, such as HDMI or A/V).

Step 2

Press the "Sound field" or "Audio field" button on your surround sound system remote control. Consult your surround sound system manual if you can't find this button as it may be labeled something slightly different depending on the brand of your system.

Select the "Pro Logic II Music" mode from the list of options, and then close the menu. You can now enjoy your MP3 files in full 5.1 surround sound.

Items you will need

  • Surround sound system with Pro Logic II support
  • MP3 audio source (e.g. CD player or DVD/Blu-ray player) connected to surround sound system
