Numpy memory error while using audio analysis using python

Question

I get the following error, while I test a more than 100 mb audio file.

Traceback (most recent call last):
File "C:\Users\opensource\Desktop\pyAudioAnalysis-master\audioFeatureExtractio
n.py", line 542, in stFeatureExtraction signal = numpy.double(signal)MemoryError

`signal = numpy.double(signal)` tries to assign the whole signal to 1 `double` floating number. — Maarten Fabré, Jul 17 '17 at 12:36
`numpy.double` will broadcast over an `ndarray` @Maarten, so that's not the problem — Daniel F, Jul 17 '17 at 13:11

Assuming your data was int16 before, by upcasting to float64, you quadrupled the size of your array. This is likely more than the memory you had left, and it threw a MemoryError
