The MP2A file extension denotes an MPEG-1 Audio Layer II stream, a digital audio compression standard defined by the Moving Picture Experts Group (MPEG). Historically utilized for digital audio broadcasting and Video CDs, this format provides efficient compression for speech and music transmission. Although largely superseded by MP3 and AAC for general consumer applications, it remains prevalent in professional broadcasting environments and poses minimal security risks.

const signature = Buffer.from([0xFF, 0xF2]);
return buffer.subarray(0, 2).equals(signature);
}
Go
func IsMP2A(data []byte) bool {
signature := []byte{0xFF, 0xF2}
if len(data) < 2 {
return false
}
return bytes.Equal(data[:2], signature)
