{"success":true,"data":{"ext":"mus","name":"MUS","description":"MUS is a simple musical score file format associated with the Interchange File Format family, originally defined for early multimedia software and maintained as a legacy format in archival tools. It was used to store compact sequence data for playback, editing, and integration in games, demo programs, and other music applications. Because it is a legacy format, support is limited today, but the files are generally low risk when handled by standard audio or viewer software.","mime":["application/vnd.musician"],"risk_level":"Safe","signatures":[{"hex":"46 4F 52 4D","offset":0,"sources":[{"name":"Wikipedia","url":"https://en.wikipedia.org/wiki/List_of_file_signatures"}]},{"hex":"53 4D 55 53","offset":0,"sources":[{"name":"Wikipedia","url":"https://en.wikipedia.org/wiki/List_of_file_signatures"}]},{"hex":"43 4D 55 53","offset":0,"sources":[{"name":"Wikipedia","url":"https://en.wikipedia.org/wiki/List_of_file_signatures"}]}],"related":[],"usage":{"python":"def is_mus(file_path: str) -> bool:\n    \"\"\"Check if file is a valid MUS by magic bytes.\"\"\"\n    signature = bytes([0x46, 0x4F, 0x52, 0x4D])\n    with open(file_path, \"rb\") as f:\n        return f.read(4) == signature","node":"function isMUS(buffer: Buffer): boolean {\n  const signature = Buffer.from([0x46, 0x4F, 0x52, 0x4D]);\n  return buffer.subarray(0, 4).equals(signature);\n}","go":"func IsMUS(data []byte) bool {\n    signature := []byte{0x46, 0x4F, 0x52, 0x4D}\n    if len(data) < 4 {\n        return false\n    }\n    return bytes.Equal(data[:4], signature)\n}"}}}
