What is an AUD file

AUD files mostly belong to WeChat by Tencent. AUD is the filename extension of voice messages sent or received via WeChat instant messenger. AUD audio messages are compressed using SILK audio compression which is optimized for speech coding. WeChat editions released before 2015 were compressed using AMR codec. Both formats use lossy compression to keep file sizes small. AUD is also the filename extension of audio projects created with Audacity audio editing software. AUD projects contain instrument adjustments, recording, and settings. A different AUD file is used to store multi-channel audio (surround sound) saved in the DTS format used in the audio mastering, cinema, radio, and movie industries. PowerDVD can decode and play AUD files containing the audio stream of DVDs. AUD filename extension is also associated with audit trails used by Oracle Database multi-model database management system. SAP ERP enterprise resource planning software, saves security audit logs in AUD files.
