音频波形隐藏

7位ASCII

解题

给了一个wav文件，打开后看波形图，放大看发现

高位为1，低位为0

110011011011001100001110011111110111010111011000010101110101010110011011101011101110110111011110011111101

ASCII是7位一组

a = '110011011011001100001110011111110111010111011000010101110101010110011011101011101110110111011110011111101'

for i in range(0, len(a), 7):
    print(chr(int(a[i:i+7], 2)), end='')
