Yet another at3+ encoder/decoder

[freefive]

This is interesting.
If one uses this tool to provide homebrew games or encoded files on the internet, maybe it's illegal.
But we do NOT.

BTW, the encoder/decoder from the PS3 SDK only supports 48khz, but the at3+ used on psp is 44.1khz.
You can try decoding at3+ files of a psp game using PS3at3tool.exe and you will find that it will not work.
