How to play AC3 files


This article discusses the options to play AC3 files (Dolby Digital audio) in several media players, some of which will be easier than others. It covers adding support for AC3 to more popular players that are based on DirectShow like Windows Media Players, while also showing some simple "download and play immediately" options.


Dolby Digital AC-3


AC3 audio mostly comes directly from DVDs and is often stored in multimedia containers with common video formats. It is important to make sure that your software is capable of playing AC3 regardless of whether you have it as a stand-alone file or not because it is likely you will need to play it eventually anyway.

Easiest Method - VideoLAN Client for Windows, MAC and Linux


With the VLC player, you can enjoy your AC3 audio files quickly. The player directly supports AC3 without the need for DirectShow filters or special codecs to be installed. If you are looking for a quick solution then this is certainly it, but if you want to look at other examples of these players or learn to play with Windows Media Player and store it in your Media Library, then read on.

You can get VLC for Windows from this URL.


Click File and click the Open File option.

Now, click the Browse button next to the first white line at the top of the window with title "Open.." and navigate through your harddrive for the AC3 file you wish to listen to and select it. After you have selected the file, click OK and VLC will start playing the AC3 audio you chose.

Play in DirectShow players such as Windows Media Player?


It is totally possible to play AC3 files in Windows Media Player and technically any DirectShow-based player. Before we look at Windows Media Player directly, let's take a look at Media Player Classic.

The first thing we need is a DirectShow filter, and there is a perfectly good one available called AC3Filter.
