get_duration can not work on generated audio <int16>

See original GitHub issue

Describe the bug

Traceback (most recent call last):
  File "tts/tts.py", line 223, in <module>
    timeDuration = librosa.get_duration(y=result, sr=sr)
  File "python3.7/site-packages/librosa/core/audio.py", line 722, in get_duration
    util.valid_audio(y, mono=False)
  File "python3.7/site-packages/librosa/util/utils.py", line 290, in valid_audio
    raise ParameterError("Audio data must be floating-point")
librosa.util.exceptions.ParameterError: Audio data must be floating-point

To Reproduce

Example:

import librosa
from tts import textToSpeech
import soundfile as sf

wav, sr = textToSpeech("hello world") # wav numpy int16 array
sf.write("result.wav", wav, sr) # it's ok.
timeDuration = librosa.get_duration(y=wav, sr=sr) # raise error
print("timeDuration",timeDuration)

Expected behavior

Get the duration from the int16 audio data.
