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/.
