On the spectrum:forensics:100pts

My friend has been sending me lots of WAV files, I think he is trying to communicate with me, what is the message he sent?
Attached files:

  • message_1.wav (sha256: 069dacbd6d6d5ed9c0228a6f94bbbec4086bcf70a4eb7a150f3be0e09862b5ed)

message_1.wav

Solution

wavファイルのようだ。
問題名の通りスぺクトログラムを見てやる。
