    Hello everyone. I'm Italian so sorry for any imperfections.
    I need to have access to the left and right channels of an audio file and apply the low pass filter, but I have not found anything about it. Have you any suggestions on how to do this?
    In Python this can be done using the library Nsound and I wondered how to use Python in Qt and possibly how to import Nsound in Qt.

      Hi and welcome to devnet,

      If you want to stay with python then look for PyQt or PySide otherwise you'll need a library like DSPFilters

      Hope it helps

        Nsound is also a C++ library and can be used in C++ applications, see http://sourceforge.net/p/nsound/code/HEAD/tree/tags/nsound-0.9.3/src/Nsound/.

        :)
