what parameter to enter in :param x: Signal

[gomez-fp]

Hi bro,
Excellent work, could you answer a question for me?
Regarding the input data :param x: Signal, I am not sure how the data should be, I am obtaining an array of Bites that gives me a digital microphone, I am obtaining it with the help of 'pyaudio.py' and I convert it to an int32 integer.
this converted data may be the input signal since when I do the exercise and measure 1k at 94dB the data does not correspond.
Could you guide me on this?
thank you.
