installation guide to use MIC_ARRAY

[nguyenvulong]

Hey guys, I am new to this product.
As I know (thanks @Neutree), MaixPy-v1 has been replaced by MaixPy (v4),
therefore this command will install v4

pip install MaixPy

My question: How to install MaixPy-v1?
I need to work with audio file, for example

from Maix import MIC_ARRAY as mic
import lcd

but the new version (v4) does not support it yet.

Thank you.
