pythonnumpyscipywavsoundfile

How can I convert a numpy array (wav data) to int16 with Python?

I have some data that I assume is wav data. If I use:

soundfile.write(filepath, my_data, samplerate)

, then it correctly writes a wav file. But I want to somehow convert that wav data to int16 as currently it's some sort of float:

[0.0018415  0.00730521 0.01155283 ... 0.10048427 0.09344029 0.08903081]

with

max 0.3002103
min -0.33075073

It came from a process in https://github.com/santi-pdp/segan_pytorch

Is there some way for me to convert to int16 this without having to save and then read a file?

Solution

  • Answer was simple enough:

    my_data = (my_data * 32767).astype(np.int16)
