Convert AUD files online for free

The .aud file extension represents a significant compatibility hurdle because it is used by two distinct, incompatible ecosystems: mobile messaging and retro gaming. Most commonly today, an .aud file is a SILK-encoded voice message created by Tencent WeChat. These files are designed for extreme compression within the app, rendering them unplayable on standard desktop software like Windows Media Player or VLC media player. Users cannot simply drag these files into a standard audio editor; they require conversion to MP3 or AAC to be archived, shared, or listened to outside the chat interface.
Alternatively, if the file originates from a PC game installation, it is likely a compressed audio asset from Westwood Studios titles (such as the classic Command & Conquer or Dune II series). These use a proprietary Westwood ADPCM compression scheme that modern audio engines cannot read natively. To use these sound effects in modding projects or preserve game soundtracks, they must be converted to WAV for editing or OGG for modern game engine compatibility. Less frequently, .aud files may be proprietary recordings from NICE Systems call centers or older Skype voicemails, both of which lock audio data inside specific codecs that require specialized conversion tools to access.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our AUD converter.
