我正在尝试使用 PyAudio 录制扬声器输出。我安装了 BackgroundMusic,它声称允许记录系统输出。我不认为这是问题所在,但我可能是错的。
代码
import pyaudio
p = pyaudio.PyAudio()
stream = p.open(
format=pyAudio.paInt16,
channels=1,
rate=44100,
input=True,
frames_per_buffer=2048
)
# code to do stuff with stream.read(), not relevant here
错误
||PaMacCore (AUHAL)|| AUHAL component not found.Traceback (most recent call last):
File ".../script.py", line 5, in <module>
stream = p.open(
File "/opt/homebrew/lib/python3.9/site-packages/pyaudio.py", line 750, in open
stream = Stream(self, *args, **kwargs)
File "/opt/homebrew/lib/python3.9/site-packages/pyaudio.py", line 441, in __init__
self._stream = pa.open(**arguments)
OSError: [Errno -9999] Unanticipated host error

根据this thread,我需要授予麦克风访问权限?在终端中运行时,它不会要求访问麦克风,而且我认为无法在系统偏好设置中添加它。
该线程还指出 this PortAudio function 作为从该错误中获取更多信息的一种方式,但我不确定如何准确地破解 PyAudio 库以获取该信息。
我希望得到一些正确方向的指导。提前致谢。
