chunk =1024# Record in chunks of 1024 samples
sample_format = pyaudio.paInt16  # 16 bits per sample
channels =2
fs =44100# Record at 44100 samples per second
seconds =3
filename ="output.wav"

p = pyaudio.PyAudio()# Create an interface to PortAudioprint('Recording')

stream = p.open(format=sample_format,
                channels=channels,
                rate=fs,
                frames_per_buffer=chunk,input=True)

frames =[]# Initialize array to store frames# Store data in chunks for 3 secondsfor i inrange(0,int(fs / chunk * seconds)):
    data = stream.read(chunk)
    frames.append(data)# Stop and close the stream 
stream.stop_stream()
stream.close()# Terminate the PortAudio interface
p.terminate()print('Finished recording')# Save the recorded data as a WAV file
wf = wave.open(filename,'wb')
wf.setnchannels(channels)
wf.setsampwidth(p.get_sample_size(sample_format))
wf.setframerate(fs)
wf.writeframes(b''.join(frames))
wf.close()
