I used to be able to play just the audio I selected in the spectral frequency display, now it plays all the audio no matter what. So here's an example of my selected audio (isn't it beautiful?), however it plays through it as though nothing is selected. It makes audio mastering very difficult since I can't listen to specific artifacts. I have already tried turning it on and off, but for all I know this is a simple problem that can be changed in the preferences. Any ideas? Please help me.
