Answer 1

Can be done with pydub:

import array
from pydub import AudioSegment
from pydub.utils import get_array_type

sound = AudioSegment.from_file(file=path_to_file)
left = sound.split_to_mono()[0]

bit_depth = left.sample_width * 8
array_type = get_array_type(bit_depth)

numeric_array = array.array(array_type, left._data)
