We are given a .wav file that is a series of high pitched noises. Opening the .wav in Sonic Visualiser and adding a spectrogram layer yields the following:


There are 8 rows of empty squares or filled in squares (0s and 1s). These yield:
111111110101010001001000001100110010000001000110010011000011010001000111001000000100100101010011001110100010000001100010011011000110000101111010011001010111101101001001010111110101101100110100010011100101111101001000001101000101101001011111010001100101010101001110010111110101011100110001010101000100100001011111010001100011000001010101010100100011000100110011010100100010000100111010001111100111110111111111

Which translates to: `ÿTH3 FL4G IS: blaze{I_[4N_H4Z_FUN_W1TH_F0UR13R!:>}ÿ`
