Ncmdump
ncmdump is a proprietary audio cache converter and binary stream decryption utility. It decrypts raw audio data from specialized music cache files and transforms them into standard audio formats.
The project functions both as a standalone tool and a cross-language conversion library. It exposes its internal decryption and conversion logic as a dynamic library, allowing the capabilities to be embedded into external applications written in different programming languages.
The utility provides batch media processing through recursive directory traversal, enabling the identification and conversion of multiple files across nested folder structures in a single operation.
