Re: How to extract sequenced data from an array?

[Ghostly]

Data file would be large for upload even if properly compressed. Easy way to 
gather similar data that comes to my mind, would involve creating 2-3 sec of 
audio WAVE data and append it over itself couple of times, then load it as 
array.

I solved the problem by using Python/Scipy:

----------------------------------------
#~ type(x) = numpy.array

for i in range(1, 1 + x.size/4):
    if (x[0, 0] == x[::i, 0]).all():
        sequence = x[:i]
        break
----------------------------------------

I thought on Scipy/Numpy as I'm familiar with Python magic. Here Scipy is used 
only to load data as 2D (2 column) array (Numpy array), but loop is in simple 
Python code, which is reasonably fast with my data ans usage

Tips mentioned here like xcorr and others will be used at some point, but as I 
already have solution to this problem I went ahead

Cheers, and thanks again for all replies
