Running Error on Spyder in windows 10

[cdyao]

I've got the following error when I run this code on Spyder in Windows 10.
Did I miss anything from installation?
Thanks

drc = muda.deformers.DynamicRangeCompression(preset=preset)
for i, jam_out in enumerate(drc.transform(j_orig)):
   ....

Do you have sox installed? This is hard thing for pip to check at install time, because sox is not a python package and does not live in the pypi dependency namespace.

Thanks!. After installing sox and place sox.exe in the same folder as my python code, it worked!
