I am learning machine learning and data analysis on `wav` files.
I know if I have `wav` files directly I can do something like this to read in the data

```
import librosa

mono, fs = librosa.load('./small_data/time_series_audio.wav', sr = 44100)

```

Now I'm given a gz-file `"music_feature_extraction_test.tar.gz"`
I'm not sure what to do now. 

I tried:

```
with gzip.open('music_train.tar.gz', 'rb') as f:
    for files in f : 
        mono, fs = librosa.load(files, sr = 44100)

```

but it gives me:

`TypeError: lstat() argument 1 must be encoded string without null bytes, not str`

Can anyone help me out?
