python-sounddevice allows you to record audio from your microphone and store it as a NumPy array. This is a handy datatype for sound processing that can be converted to WAV format for storage using the scipy.io.wavfile module. Make sure to install the scipy module for the following example ( pip install scipy ).

Short Tutorial — simpleaudio 1.0.4 documentation
https://simpleaudio.readthedocs.io/en/latest/tutorial.html
Numpy arrays can be used to store audio but there are a few crucial requirements. If they are to store stereo audio, the array must have two columns since each column contains one channel of audio data. They must also have a signed 16-bit integer dtype and the sample amplitude values must consequently fall in the range of -32768 to 32767.
