In this Audacity 4 intro video, there is a cool effect in the audio. I have no idea what it is called. But when you wear headphones, you can hear tones go left and right many times. I think this is a cool effect and would like to learn, how can I do this in my own audio editing? It kinda feels like an audio worm going through my head from my right ear to my left ear and back to my right ear again, but many times.
Thank you.
