Why I'm getting different sampling rate for same wav file with different libraries?

I'm trying to get the sampling rate of wav file using several python libraries, and I'm getting different results:

(1):

import wave
wave_file = wave.open(fname, 'rb')
frame_rate = wave_file.getframerate()

output of frame_rate = 16000

(2):

from scipy.io.wavfile import read as read_wav
sampling_rate, data = read_wav(fname)

output of sampling_rate = 16000

(3)

import librosa
X, sample_rate = librosa.load(fname)

output of sample_rate = 22050

Why the output of librosa library is different ?

Because librosa.load() makes a resampling to that frequency if you don't specify the keyword argument sr.
