Pointers

Hi All,



We have this issue with SWIG it was our first time and it all worked perfect apart from pointers!



We wrapped C++ code to use in python we are stuck with this function the audioBuffer pointer is meant to take a 32bit floating array.



DecodeAudioBuffer(float *audioBuffer, int size);





We Used portaudio to record audio to a numpty array:



stream = p.open(format=pyaudio.paInt16, channels=1, rate=RATE, input=True, frames_per_buffer=CHUNKSIZE)



frames = [] # A python-list of chunks(numpy.ndarray)

for _ in range(0, int(RATE / CHUNKSIZE * RECORD_SECONDS)):

    data = stream.read(CHUNKSIZE)

    frames.append(numpy.frombuffer(data, dtype=numpy.int16)) #/ 32768.0



#Convert the list of numpy-arrays into a 1D array (column-wise)

numpydata = numpy.hstack(frames)







/* OxySDK interface */

%module OxySDK



%include "stdint.i"

%include "carrays.i"

%include cpointer.i



%{

#define SWIG_FILE_WITH_INIT

#include "Lib_api.h"

%}



%include "numpy.i"

%init %{

import_array();

%}



%pointer_functions(double ,doubleP)



%include "Lib_api.h"







Any ideas how we can record in python and pass it our pointer
