Description
A .dat file whose contents are encrypted with a simple XOR key. WeChat stores the images from its chats this way, and some other apps do the same with sound and documents. Filestar finds the key and restores the original file, such as a JPEG, PNG or GIF.
Compressed audio file similar to an .MP3 file, but offers several performance improvements; examples include a higher coding efficiency for both stationary and transient signals, a simpler filterbank, and better handling of frequencies above 16 kHz; maintains quality nearly indistinguishable from the original audio source.
