[python]“一把十首”倒放“我是傻b”驗證

大家有沒有看過“一把十首”倒放變成“我是傻逼”視頻？

我現在利用python的pyaudio進行驗證一下。

自己錄一段語音

<code>

wave
import
 
pyaudio
 
CHUNK

1024
FORMAT

pyaudio.paInt16
CHANNELS

WAVE_OUTPUT_FILENAME

p

pyaudio.PyAudio()
 
stream
 = 
p.open(format=FORMAT,

frames
 = 
[]
for
 
i in range(0, int(RATE / CHUNK * RECORD_SECONDS)):
    
data
 = 
stream.read(CHUNK)
    
frames.append(data)

  
done recording")
 
stream.stop_stream()
stream.close()
 
p.terminate()
 
wf
 = 
wave.open(WAVE_OUTPUT_FILENAME, 'wb')
wf.setnchannels(CHANNELS)
wf.setsampwidth(p.get_sample_size(FORMAT))
wf.setframerate(RATE)
wf.writeframes(b''.join(frames))
wf.close()
/<code>

播放&倒放

<code>
import
 pyaudio  
import
 wave  
import
 sys  
  
 
chunk = 
160

 
f = wave.open(
r"ybss.wav"
,
"rb"
)  
p = pyaudio.PyAudio()  
  
 
stream = p.open(format = p.get_format_from_width(f.getsampwidth()),  
                channels = f.getnchannels(),  
                rate = f.getframerate(),  
                output = 
True
)  

 
data = f.readframes(chunk)
pdata = data
mdata = data
  
 
while
 data != 
b''
:  
     
     
    pdata = pdata + data
    mdata = data + mdata
    data = f.readframes(chunk)  
print(
"正放"
, len(pdata))
stream.write(pdata)
print(
"倒放"
, len(mdata))
stream.write(mdata)

 
stream.stop_stream()  
stream.close()  
  
 
p.terminate()  


 
frames = []
frames.append(pdata)
frames.append(mdata)
wf = wave.open(
r"ybss_p.wav"
, 
'wb'
)
wf.setnchannels(f.getnchannels())
wf.setsampwidth(f.getsampwidth())
wf.setframerate(f.getframerate())
wf.writeframes(
b''
.join(frames))
wf.close()/<code>

以上代碼實現正放和倒放，可以體驗一下是不是變成“我是傻b了”

附上音頻感受一下：

為什麼呢？好神奇！！
