Sampling rate issue with Librosa
<p>When doing a STFT, and then an inverse STFT (iSTFT) on a 16 bits 44.1 khz audio file with the library <a href="https://github.com/librosa/librosa" rel="noreferrer">Librosa</a> :</p>

<pre><code>import librosa

y, sr = librosa.load('test.wav', mono=False)
y1 = y[0,]
S = librosa.core.stft(y1)
z1 = librosa.core.istft(S, dtype=y1.dtype)
librosa.output.write_wav('test2.wav', z1, sr)
</code></pre>

<p>the output is only a 22 khz audio file. Why? Where is there the sampling rate change in librosa ?</p>
