I have begun creating an application that will later require intricate audio processing. The sort of functions I am looking for are as follows: - To be able to load WAV files. - To be able to start a sound and stop a sound before the end of the sample. - To be able to change the pitch of a sound. - To be able to apply EQ effects to a sound. I am working within QT and would like to keep it within the QT libraries. So which libraries would I be able to use?
