如何使用pyaudio在macos上录制麦克风?

我在Windows10上用python制作了一个简单的语音助手,带有语音识别功能,我也想复制macOs的代码

我下载了PortAudio和PyAudio,代码运行正常,但当我播放音频曲目时,我什么也听不到:((当我尝试使用语音识别时,程序没有检测到)
我猜是有权限之类的东西…有人有主意吗

(我还检查了我是否使用了正确的设备索引,我确实使用了索引0(Mackbook内置麦克风)

下面是一些代码示例:

import pyaudio
import wave

chunk = 1024  # Record in chunks of 1024 samples
sample_format = pyaudio.paInt16  # 16 bits per sample
channels = 1
fs = 44100  # Record at 44100 samples per second
seconds = 3
filename = "output.wav"

p = pyaudio.PyAudio()  # Create an interface to PortAudio

print('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 seconds
for i in range(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()

我找到了答案

实际上,代码一直运行良好😅, 问题是我使用了Visual Studio Code,由于某种原因,它弄乱了麦克风权限🤦‍♂️
现在我用python [filename].py通过终端运行代码,它工作得很好
