Convert Audio files (AUD) online for free
The converter easily converts your AUD Files to various formats - free and online. No WeChat or or other Audio software needed.
To convert other file formats to the "Proprietary Voice Recording" file type, you need software like WeChat or a similar tool.
The .aud file extension is a massive catch-all format heavily fragmented across entirely different industries. Most commonly, it functions as a SILK-encoded voice message used by Tencent WeChat or old Skype voicemails. Alternatively, retro gaming enthusiasts will encounter .aud as compressed audio tracks (often using ADPCM in a RIFF container) from classic Westwood Studios games like Command & Conquer or Dune 2. In enterprise IT environments, .aud files serve an entirely different purpose: storing plain text or binary database audit trails for Oracle Database or SAP systems. Finally, they can be proprietary, encrypted voice recordings from NICE Systems recorders or Olympus dictation hardware.
This fragmentation is the primary disadvantage of the format. A generic media player like VLC or Windows Media Player will almost certainly fail to play an .aud file natively because the extension does not dictate the underlying codec. Furthermore, enterprise .aud voice recordings are often encrypted for compliance, meaning they cannot be opened without the original corporate software. WeChat and Skype .aud files are locked into the SILK codec, which is highly efficient for streaming but completely unsupported by standard audio editors or web browsers.
To make an .aud file usable, you must convert it based on its true internal format. For web use and playback of voice messages or game audio, convert to MP3 for maximum compatibility across all devices. If you are archiving or intend to edit the audio in software like Audacity, convert to WAV. If your .aud file is a database log, converting it to TXT or CSV makes it readable. Drag and drop your file here to analyze and convert it securely right in your browser - free, online, and without installing software.
