How to Open Aud File on a Computer

Before anything else, let's answer the basic question: What is a .Aud file anyway? You may have just recently encountered one are curious about what this could be. Like the name implies, this is a file extension for audio files. It's not as common as .wav or .MP3, but that's because it has a specialized purpose.

It was originally developed by Westwood Studios to use in their games. Because space is limited when you're dealing with video games, they created a highly compressed format called .Aud that could still nonetheless deliver very good audio quality.

Nowadays, .Aud is not only used for games, it is also used in the app WeChat to store audio recordings.

Even though .Aud is not very common, it can still be opened on a few media players, including NICE Media Player as well as WinAmp (if you add a special plugin). In addition, it can be converted to .MP3 or .WAV for easier portability.

How Do You Open a .Aud File on a Windows Computer?

Though, as we discussed, there is software that can play .Aud files natively, it is easier to simply use a converter to convert .Aud files to .MP3 or .WAV and listen to them that way. Because they are high quality, they convert fairly well.

A good application to use is Louyue Audio Player (Chinese: 楼月语音播放器). It is free and has a very easy interface. You can simply drag the files to the player and you can listen to them right away. If you need, you can download the program from here: Louyue Audio Player.

How Do You Open a .Aud File on a Mac?

Unfortunately, since Mac OSX is still not quite as "open" as Windows, it's a little harder to play unusual formats like .Aud. There s a method to do this, though, but you will have to convert the .Aud files into .WAV before you can listen to them.

Converting to .WAV is also sort of involved, but it can be done. Since there is no software with a graphical user interface that can play or convert .Aud on the Mac (that we know of), you will have to use the command line interface. Make sure that you're comfortable using a terminal.

In actuality, even among the command line utilities, there is none that will convert .Aud out of the box. It will take a bit of tweaking first. You will have to use a special script.

Follow these steps:

(1) Download Python 2.7.

(2) Download a conversion script here: https://gist.github.com/Kronopath/c94c93d8279e3bac19f2. Do this before you do anything else.

(3) Download a SILK audio decoder. You can do so here: https://github.com/Kronopath/SILKCodec. It will come as a zip file. You will need to go into the SILK_SDK_SRC_ARM folder. It should have a MakeFile already in it. Go into the terminal, change directories to this folder, then run "make lib", then "make decoder". The results should be a library file called libSKP_SILK_SDK.a and a utility called "decoder." Copy these into the same folder that the conversion script will be in.

(4) Download ffmpeg for OSX. This is an audio utility that uses the command line interface of OSX.

(5) Download a C compiler, like XCode.

(6) Now place all your .aud files into the same folder together to make things easier.

(7) Run this command in the terminal: "python converter.py --silk-decoder [the path to the decoder] [the path to your folder with the .aud files]".

(8) Now wait while the audio converts. The result should be a folder with .WAV files.

After that, it's easy to use a standard converter to convert the .WAV files to other, more common formats. Since .WAV files are non-lossy, they contain a lot of data and so tend to be high-quality. You don't have to worry about much data loss when converting from .Aud. However, because of these same features, .WAV files can be rather large. If you don't want audio files that will take up a lot of space, it's recommended that you convert the .WAV files to .MP3 afterwards.

While .Aud files are not very common, there are ways to convert and listen to them. It may be easier on Windows, but it's not totally impossible on Mac OSX, either. Just make sure that you know how to use the terminal and deal with Python scripts and you can convert your .Aud files within a few minutes.
