I have a signal in Python, and I want to hear it. This is possible?.
The data is in the format numpy.ndarray.
In Matlab one can use the command sound(data,f).

Combine that dupe target ("create a sound file") with [this](https://stackoverflow.com/questions/260738/play-audio-with-python) ("play a sound file"). The latter has a numpy array-based answer down somewhere, perhaps that's better as a dupe target. – Andras Deak -- Слава Україні Feb 13 '19 at 22:30

Yep! You can use scipy.io.wavfile library
import numpy as np
from scipy.io.wavfile import write
noise = np.random.uniform(-1,1,100000)
write('noise.wav', len(noise), noise)

1We cannot run your example because the variable `data` is not defined. Please consider testing before posting. – Leonard Oct 05 '19 at 12:23

You can use the module soundfile:
import soundfile as sf
sf.write(filename.wav, data, samplerate)
For further information read the documentation.
