Use cases
- convert ncm files to mp3
- decrypt netease cloud music downloads
- batch convert ncm music library
- recover mp3 from ncm format
- play netease music outside its app
When to choose
- you have NCM files downloaded from NetEase Cloud Music and want standard MP3/FLAC files
- you prefer a simple GUI or CLI on any platform with Java installed
When to avoid
