Hello ZenHAX users!
I have been attempting to extract an archive with .wav files in it, however when I extracted it I found it is sped up (even with correct bits and freq) and covered up with static, so I came to the conclusion it is compressed. I first checked the quickbms algo identifying page, however, I didnt find any reference to the bytes at the start of the file. Theres two files (one with extension .ss0 and one with .sl0, but both serve the same purpose) with the first 4 bytes being the same so I am assuming that the comtype for them is the same, there is also no uncompressed size for these files.
These first four bytes are essentially 0x05 or 05 00 00 00 (little endianness)
If this is a very simple thing than I'm sorry however I couldn't find it anywhere else.
