process_google.py MemoryError

[pushkalkatara]

The script process_google.py reads all the .wav in a numpy array which might cause a memory error on many systems.
Either use of disk storage through numpy.memmap or storing array as .HDF5 with PyTables or use of some library like Pandas might solve this issue.
