When I change input=True instead than I get a lot of errors:
Traceback (most recent call last):
File "sound.py", line 19, in <module>
rate=RATE, input=True, frames_per_buffer=CHUNK)
File "/usr/lib/python3/dist-packages/pyaudio.py", line 747, in open
stream = Stream(self, *args, **kwargs)
File "/usr/lib/python3/dist-packages/pyaudio.py", line 442, in __init__
self._stream = pa.open(**arguments)
OSError: [Errno Invalid number of channels] -9998
I don't think we can solve those errors
Anyway thanks for helping me out so far.
