{"success":true,"data":{"ext":"m3a","name":"M3A","description":"M3A is an MPEG audio file format associated with the MPEG standards family, maintained by the ISO and IEC committees. It is used for storing compressed audio for playback in media players, archives, and distribution workflows that rely on MPEG-compatible sound streams. The format is generally safe, though files from untrusted sources should still be checked for corruption or malformed metadata, as with other legacy audio containers and streams.","mime":["audio/mpeg"],"risk_level":"Safe","signatures":[{"hex":"FF F2","offset":0,"sources":[{"name":"Apache Tika","url":"https://raw.githubusercontent.com/apache/tika/main/tika-core/src/main/resources/org/apache/tika/mime/tika-mimetypes.xml"}]},{"hex":"FF F3","offset":0,"sources":[{"name":"Apache Tika","url":"https://raw.githubusercontent.com/apache/tika/main/tika-core/src/main/resources/org/apache/tika/mime/tika-mimetypes.xml"}]},{"hex":"FF F4","offset":0,"sources":[{"name":"Apache Tika","url":"https://raw.githubusercontent.com/apache/tika/main/tika-core/src/main/resources/org/apache/tika/mime/tika-mimetypes.xml"}]},{"hex":"FF F5","offset":0,"sources":[{"name":"Apache Tika","url":"https://raw.githubusercontent.com/apache/tika/main/tika-core/src/main/resources/org/apache/tika/mime/tika-mimetypes.xml"}]},{"hex":"FF F6","offset":0,"sources":[{"name":"Apache Tika","url":"https://raw.githubusercontent.com/apache/tika/main/tika-core/src/main/resources/org/apache/tika/mime/tika-mimetypes.xml"}]},{"hex":"FF F7","offset":0,"sources":[{"name":"Apache Tika","url":"https://raw.githubusercontent.com/apache/tika/main/tika-core/src/main/resources/org/apache/tika/mime/tika-mimetypes.xml"}]},{"hex":"FF FA","offset":0,"sources":[{"name":"Apache Tika","url":"https://raw.githubusercontent.com/apache/tika/main/tika-core/src/main/resources/org/apache/tika/mime/tika-mimetypes.xml"}]},{"hex":"FF FB","offset":0,"sources":[{"name":"Apache Tika","url":"https://raw.githubusercontent.com/apache/tika/main/tika-core/src/main/resources/org/apache/tika/mime/tika-mimetypes.xml"}]},{"hex":"FF FC","offset":0,"sources":[{"name":"Apache Tika","url":"https://raw.githubusercontent.com/apache/tika/main/tika-core/src/main/resources/org/apache/tika/mime/tika-mimetypes.xml"}]},{"hex":"FF FD","offset":0,"sources":[{"name":"Apache Tika","url":"https://raw.githubusercontent.com/apache/tika/main/tika-core/src/main/resources/org/apache/tika/mime/tika-mimetypes.xml"}]},{"hex":"FF E3","offset":0,"sources":[{"name":"Apache Tika","url":"https://raw.githubusercontent.com/apache/tika/main/tika-core/src/main/resources/org/apache/tika/mime/tika-mimetypes.xml"}]},{"hex":"49 44 33","offset":0,"sources":[{"name":"Apache Tika","url":"https://raw.githubusercontent.com/apache/tika/main/tika-core/src/main/resources/org/apache/tika/mime/tika-mimetypes.xml"}]}],"related":["m2a","mp2","mp2a","mpga","mp3"],"usage":{"python":"def is_m3a(file_path: str) -> bool:\n    \"\"\"Check if file is a valid M3A by magic bytes.\"\"\"\n    signature = bytes([0xFF, 0xF2])\n    with open(file_path, \"rb\") as f:\n        return f.read(2) == signature","node":"function isM3A(buffer: Buffer): boolean {\n  const signature = Buffer.from([0xFF, 0xF2]);\n  return buffer.subarray(0, 2).equals(signature);\n}","go":"func IsM3A(data []byte) bool {\n    signature := []byte{0xFF, 0xF2}\n    if len(data) < 2 {\n        return false\n    }\n    return bytes.Equal(data[:2], signature)\n}"},"category":"Audio"}}
