Open

in the .zip file contains a wav audio file

Upon listening to the audio file closely, you will realise that there is 2 different types of beeps

long ones, and short ones

the long ones are a representation of 1

the short ones are a representation of 0

Solving

by listening to the audio file and pressing 1 everytime we hear a long beep, and 0 everytime we hear a short beep, we will end up with the following binary (eventually)

01100110 01101100 01100001 01100111 01111011 01101101 00110000 01110010 01110011 00110011 01011111 01100010 01110101 01010100 01011111 01100010 00110001 01101110 01000001 01110010 01111001 01111101

when converted to ascii from binary, we get the flag: flag{m0rs3_buT_b1nAry}

flag: flag{m0rs3_buT_b1nAry}
