AttributeError: '_io.BufferedReader' object has no attribute

import wave
from zlib import compress

source = open("rickroll.wav", mode="rb")
nframes = source.getnframes()
source_frames = source.readframes(nframes)
data_compress = compress(source_frames, level=6)
fout = open('nto.bin', 'w')

print(data_compress, file=fout)
fout.close()

данный код выдает ошибку

File "C:\Users\...", line 6, in <module>
    nframes = source.getnframes()
AttributeError: '_io.BufferedReader' object has no attribute 'getnframes'

подскажите решение

используя wave.open()

File "C:\Users\1-ПК\PycharmProjects\pythonProject\cringe\new.py", line 5, in <module>
    source = wave.open("rickroll.wav", mode="rb")
  File "C:\Users\1-ПК\python38\lib\wave.py", line 509, in open
    return Wave_read(f)
