overview
Convert Netease Cloud Music ncm files to mp3/flac files
history
ncmdump is a small C++ command-line converter for NetEase Cloud Music `.ncm` cache files. Its README describes converting downloaded NCM cache files to MP3 or FLAC and the Homebrew formula packages the same purpose.
The GitHub repository was created on 2021-10-06. The README says this C++ version was a cross-platform port and reproduction of the earlier anonymous5l/ncmdump project, which the README says had been deleted, and claims it was the earliest C++ version and first program on the market to support NCM conversion. Version 1.3.0 is called out in the README for fixing filenames containing UTF-8 characters such as Chinese, Japanese, Korean, and emoji, and for adding DLL builds for use from other languages.
ncmdump's adoption is concentrated in the NetEase Cloud Music ecosystem and Chinese-language toolchains. The GitHub page observed for this batch showed about 4.1k stars and 488 forks, while Homebrew, MacPorts, and winget packaging make the CLI available outside ad-hoc binary downloads. The Homebrew formula API response consulted for this July 2026 batch reported 68 install-on-request events in 30 days and 649 in 365 days.
The README documents single-file conversion, multiple input files, directory mode with `-d`, recursive traversal with `-r`, output selection with `-o`, source deletion after successful processing with `-m`, and version/help flags. The maintainer has clarified in GitHub Discussions that the tool decrypts and extracts the original MP3 or FLAC data from the `.ncm` file rather than transcoding between formats.
ncmdump is a format-escape utility: valuable when a user's music files are locked in NetEase's `.ncm` wrapper and they want normal player/library compatibility. It is niche, but the packaging story matters because users often need a trusted binary instead of random converter sites.
