問題：python在window上錄多麥數據報錯：python OSError: [Errno -9998] Invalid number of channels  ？
import pyaudio
import wave
CHUNK = 1024
FORMAT = pyaudio.paInt16
CHANNELS = 6
RATE = 16000
RECORD_SECONDS = 5
WAVE_OUTPUT_FILENAME = "record.wav"
p = pyaudio.PyAudio()
stream = p.open(format=FORMAT,channels=CHANNELS,rate=RATE,input=True,frames_per_buffer=CHUNK)
print("* recording")
frames = []
for i in range(0, int(RATE / CHUNK * RECORD_SECONDS)):
   data = stream.read(CHUNK)
   frames.append(data)
print("* 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()

          

? ?首先, 在網址：https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyaudio找到對應的版本，下載下來，

然后，將python原有的pyaudio卸載掉，pip install??PyAudio-0.2.11-cp36-cp36m-win_amd64.whl? 即可。
