Given was an audio file (recorded.mp3) which contains information encoded inthe high frequencies (about 12 KHz to 20 KHz) of the frequency spectrum. Tosee these information, open the file in audacity and change to the frequencyspectrum view. Note that you have to change the default settings there toinclude high frequencies up to 22 KHz (default is up to 8 KHz). You will seelonger and shorter bars (see audacity.png). Longer bars encode a 1, whileshorter bars encode a 0. Reading all bars will result in the following bitpattern:
    01101111    01101100    01101111    01100001    01000011    01010100    01000110    01111011    01001110    00110000    01110100    01011111    00111100    01101100    01101100    01011111    01100011    00110100    01101110    01011111    01100010    00110011    01011111    01101000    00110011    00110100    01110010    01100100    01111101
If you group them into items of 8 bit you get an ASCII representation of theflag, which is: `VolgaCTF{N0t_4ll_c4n_b3_h34rd}`
